When performing a spell check in LO Writer, pressing Alt+G to ignore a spelling results in the dialog toggling between the Ignore All and Close buttons.

Can somebody confirm this behavior?

Any idea of the cause or how to fix?

Using LO 4.2.4.

Thanks.

Sorry but how do you perform a spell check? I select a language for my document and it does it the check "on the fly". If it doesn't find a word in it's dictionary then it underlines the word in red. Right-clicking on the underlined word opens a menu including various choices for "correct" spellings and other choices such as changing the language defined for the document you're editing. Alt+G doesn't do anything that I can see. Maybe you could be a bit more explicit about how you do the spell check.
I'm also using LO 4.2.4 so I guess I cannot confirm your problem.

Some of us find automatic checking irritating and we press F7 when we want to. Personally, I've stuck to OpenOffice and Alt+G works there.

One of the options on the menu is Set language for selection and one of the options is None, Do not check spelling.

Press F7. Real-time/on-the-fly spell checking is disabled and instead performed manually. Might not satisfy your work flow but lots of people work this way because the red underlining is distracting. Everybody is different.

I tested with a fresh profile and the bug remains. Thus the problem is not profile corruption.

That isn't quite what it is doing. Notice first that there are 2 buttons with Alt+C as their accelerator: Close and Correct. Pressing Alt+C toggles focus between them, without activating either. I suppose this is the correct behavior whenever an accelerator is ambiguous. You pick one, then press Space to activate the button.

Now notice that Alt+G is the accelerator for both Ignore All and for the Check Grammar box at the bottom left. While it looks like pressing Alt+G toggles between Close and Ignore All, it is actually toggling between Ignore All and Check Grammer, the two functions with Alt+G accelerator. I think the Close button also gets a highlight when Check Grammar is selected, because Check Grammar is not a button, and there needs to be a default button. When Alt+G picks Check Grammar, pressing Space will activate that, while pressing Enter will activate the default button, Close.

Thanks for helping ljb643. I now see what you described.

Now how to fix the problem? I have used my keyboard to perform spell checks for 20+ years. Using a mouse is a nuisance, and slower.

The bug is not in the behavior, but in the duplication of accelerators on the dialog. Similar bugs on other dialogs (see below) have been reported, and some were fixed. So consider opening a bug report for this. You should describe the difficulties caused by duplicate accelerators with this specific dialog.

The fix is for them to assign a different accelerator to one of the duplicate functions. For example, 'Check Grammar' could be Alt+M, leaving 'Ignore All' as Alt+G. 'Correct' could be changed to Alt+T or Alt+O.
