I am on a x86-64 openSUSE 11.0 system, trying to run Firefox 3.0.3 on a Windows 2003 Server using SeamlessRDP. Whenever I try to do so, no new window appears; instead, I get the following output to the console:
$ rdesktop -A -s 'c:\seamlessrdp\seamlessrdpshell.exe C:\Program Files\Mozilla Firefox\firefox.exe' tmobile1
Autoselected keyboard map en-gb
WARNING: Broken Window Manager: doesn't handle restack (window was moved to bottom)
WARNING: Remote desktop does not support colour depth 24; falling back to 16
This occurs with both the openSUSE 11.0 stock rdesktop-1.5.0 RPM, and also rdesktop-1.6.0 compiled from sources.
If I instead remotely run another program which happens to launch Firefox, the same problem occurs.
