LinuxQuestions.org - How to get rid of annoying "bouncing window" on desktop

Hi all -

I use Linux Mint (and have no problems with that) but I've also been trying out a number of other live-CD distros in the last couple of days.
With several of them, they work perfectly but I get a very annoying "bouncing window" moving around the screen. It says "Attention - input not supported". ( That is nonsense - I can use the mouse and keyboard, use apps, everything....).

( Btw - I have an LCD monitor - it is 1280x1024 resolution ).

Of the distros I've been trying, I first came across this in grml Linux (and have asked for help at that distro's site), but this problem doesn't seem to be specific to a single distro. What I mean by that is that it's not like (say) an error message appearing at boot-time which would be likely to be specific to a given distro's code.

I've had a couple of suggestions from the grml users which were as follows -
a) Try booting with "nofb"
b) Try booting with "fb800x600"
c) Check the "OSD menu" on my monitor ( I was unable to get that to appear, even though there is a "menu" button on the front of my monitor)
d) (UPDATE) - I've just tried booting with "fb1280x1024" and that didn't make the window disappear either.

In short, none of the above things made the window disappear.

So, I'd be "over the moon" if anyone can let me know what causes this window to appear, and (even better) how to get rid of it.

I have a screenshot of the annoying window in action ( actually, a photo taken by my cellphone camera - I don't have a digital camera ) - here's the URL for it -
