If you use the Lightning calendar add-on with Seamonkey or Thunderbird, read this before applying yesterday's Slackware patches to Seamonkey-2.22.1 and/or Thunderbird-24.1.1:

Thunderbird-24.1.0 (pre-patch) requires Lightning-2.6.2

After applying the Slackware patch to Thunderbird-24.1.1, you must upgrade to Lightning-2.6.3.

Seamonkey-2.22 (pre-patch) requires Lighting-2.7b1

I have not found any released version of Lightning that works with the patch Seamonkey-2.22.1. I tried Lighting-2.7b1, 2.6.2, 2.6.3, and 2.8b1. Except for 2.8b1 (which does not install at all), they all start, but the calendar is empty and non-responsive. I don't know yet if this is Slackware-specific (like this one was) or not.

I don't see any mention of Seamonkey on recent posts on the Lightning blog (all the discussion has been about a surprise Thunderbird incompatibility).

According to https://bugzilla.mozilla.org/show_bug.cgi?id=941217 it is a known issue and the comments suggest it will be fixed in Seamonkey 2.23.

Thanks for that.

Actually the comments say "I would assume the next Seamonkey Beta build should pick up the fix", not specifically mentioning 2.23 (which would require a new version of Lightning, starting the process over again?) This is not encouraging. Seamonkey-2.22.1 is a security fix, and anyone using Lightning with it has to choose between giving up Lightning until some future release, or keeping an 'insecure' browser.

Seamonkey-2.23 has been released, but no version of Lightning works with it - even though one of the documented fixes is "Fixed incompatibility with binary extensions such as Lighting (bug #915574)".

I tried Seamonkey-2.23 on Slackware 14.1 and Lighting-2.8b1 still does not work.

Mozilla bug #941217 says it won't work until Lightning is rebuilt. Watch for Lighting-2.8b2.

Lightning 2.6.4, will work with SeaMonkey Mail 2.22.1.

You might check this list for a working version of Lightning for whatever version of SeaMonkey you maybe running,

https://addons.mozilla.org/en-US/sea...#version-1.9.1

Exactly this sort of bug makes me secretly wish for some Holy Boot Of Wrath to come down from heaven and kick some developers' butts until they get their act together.

D'accord, mon ami.

No, this is wrong. Have you tried it? I did. It doesn't work.

I know what the addons page says - that Lightning-2.6.x are for Seamonkey-2.21.x (note 2.21, not 2.22 as you said), but there is more accurate information here: https://developer.mozilla.org/en-US/...endar_Versions

You will see how messed up this situation is. Lightning-2.6.1, 2.6.2, 2.6.3, and 2.6.4 are not listed as compatible with ANY version of Seamonkey. They were supposed to work with Seamonkey-2.21.x (as per the addons page) but they don't due to a library mismatch. Seamonkey-2.22.x requires Lightning-2.7.x, but the only available one (2.7b1) is not compatible with the seamonkey-2.22.1 (which is the current Slackware patch). Seamonkey-2.23.x requires Lightning-2.8.x but the only available one (2.8b1) is not compatible with the latest release Seamonkey-2.23 (even the page I linked to is wrong on this).

The reason is library versions. Seamonkey-2.22 provides the symbol "xul25.0" in libxul.so, Seamonkey-2.22.1 provides "xul25.0.1", and Seamonkey-2.23 provides "xul26". Lightning-2.7b1 expects to find "xul25.0", and Lightning-2.8b1 expects to find "xul26.0".

Here you go:

That shows Seamonkey-2.22.1 with Lightning behind it. You say that is Lightning-2.6.4?

This: https://developer.mozilla.org/en-US/...endar_Versions
And this: https://addons.mozilla.org/en-US/sea...ning/versions/
And this: https://bugzilla.mozilla.org/show_bug.cgi?id=941217

all say that it can't work. Seamonkey-2.22 requires at least Lightning-2.7. My experience matches that.

Just to be sure, you can see events on the calendar, and click on calendar days to create or open events? (Because for me, as well as those posting in the bug report above, Lightning loads but the calendar is empty and non-responsive.)

If it does work for you, then I have no idea what is going on.

A Slackware 14.1 patch for seamonkey-2.24 was released today. This version works with Lightning-2.9b1 which is available at lighting extension downloads page. I believe this is the first version of Seamonkey that had a working Lightning add-on available in about 2 months.

Yep, I can confirm that we have a working calendar for Seamonkey again, finally. 2.9b1 is obviously still Beta, after so many years. I hope, they will reach 3.0 soon and stabilise things. It's just bad practice to break interfaces, every so often. This indicates a fundamental weakness in the plug-in architecture, IMHO.

If this happens again with another version any time soon, I am done with Seamonkey, I am afraid, although in general I like this internet suite a lot, otherwise.

Installed 2.9b1 and it appears blurred, as in fuzzy, and hard on the eyes. Anyone else notice this?
BTW, eye drops didn't help.

Nope, looks as always/as it should, here.
