This was reported in bug 642423 comment 15.

STR:
1. Move one of Adobe InDesign's panels in front of a Firefox window.
2. Move your mouse over a point where the Firefox window has a bookmarks button
   which is covered by the InDesign panel.

Now a tooltip appears and the button has mouseover feedback, which shouldn't happen.

The problem is that Firefox thinks the panel is transparent to mouse events.

The panel has window level kCGFloatingWindowLevel, which we treat as transparent. We shouldn't do that.
I tried to reproduce the Jing window problem I had when I originally wrote this code, but Jing seems to have changed its behavior in the meantime: it now removes its window properly instead of only making it transparent.
We've added the window alpha check in the meantime, so that should make us robust anyway, I think.

Does this apply also to any other windows that are dragged in front of Firefox, or does it only apply to Adobe InDesign's panels. I am asking this because I would like to verify this but I don't have Adobe InDesign installed.

Thanks!

This is not specific to Adobe InDesign, but I think you will have a tough time finding non-Adobe applications that exhibit this. Theoretically anything that uses kCGFloatingWindowLevel windows will see it. (Perhaps Markus knows of some others?)

Note that you can download and install a 30-day free trial of InDesign from http://www.adobe.com/cfusion/tdrc/index.cfm?product=indesign

I don't know of any others, no; it's likely that other Adobe apps like Photoshop use kCGFloatingWindowLevel, too, but I haven't tested.
