Occasionally when I move several Firefox windows from one desktop to another using the pager, one of the windows changes its properties.
The NoTitle and WindowListSkip flags somehow turn true.
Look the FvwmIdent output for such a “modified” window]http://farm8.staticflickr.com/7584/17017700402_964cb0e94d_z.jpg[/url]
For comparison, here the FvwmIdent output for another Firefox window that didn’t get its attributes changed]http://farm8.staticflickr.com/7645/16396730274_aff6c37197_z.jpg[/url]
Any idea what could be the reason for that strange behavior?
