Comment 32 for bug 940603

Chris, All,
I believe the "exe" windows are embedded windows from browser plugins. So with flash for example they are probably created by the process I can see:
/opt/google/chrome/chrome --type=plugin --plugin-path=/usr/lib/adobe-flashplugin/libflashplayer.so

This also supports smspillaz' theory (he told me) that it's to do with reparenting of X windows. I imagine any window created by a plugin process gets reparented into the main browser window. Looking at "xwininfo -all" seems to support this.

Does anyone find any part of their web pages/apps are missing/broken in their chrome window when the white box appears?
