Flutterby™! : Bug of the moment

Interesting bug of the moment (described as non-techically as possible so I don't alienate both of my remaining non-geek readers): In my map browser, I trap the "mouse move" event, and if the cursor is over a thumbnail, I start a timer. If I haven't seen another "mouse move" in a short time (two seconds or so), I pop up a larger view of the image (which then goes away if you move the mouse or do anything else).

If the right combination of overlapping windows occurs, you can move the mouse cursor off of the map window on to another application, but with the timer still counting down and the window no longer registering mouse motion, two seconds later that larger image pops up over... say... my editor. Confused the hell out of me the first time I saw it.

Konqueror exhibits the same bug.

I'm not sure if I'm going to fix it, 'cause it's kinda cool in a surrealist sort of way.
