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.
Attached patch patch (obsolete) — Splinter Review
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.

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
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.
