Comment 12 for bug 702452

Trevino, Firstly I failed to say that the changes in post 10 only come into effect after a logout and login - it seems that Unity does some matching at startup. Also .desktop files on the Desktop are not included in this 'matching' and a StartupWMClass=Wine in them have no effect when run. All of my .desktop files were created a long time ago by earlier versions of wine and all had the line - I used a command similar to the one above to find and grep for them before (and after) making the changes.

Typical files before changes were:

[Desktop Entry]
Name=Macromedia Dreamweaver MX 2004
Exec=env WINEPREFIX="/home/pcurtis/.wine" wine "C:\\Program Files\\Macromedia\\Dreamweaver MX 2004\\Dreamweaver.exe"
Type=Application
StartupWMClass=Wine
Path=/home/pcurtis/.wine/dosdevices/c:/Program Files/Macromedia/Dreamweaver MX 2004
Icon=9296_dreamweaver.0

[Desktop Entry]
Name=IrfanView 3.95
Exec=env WINEPREFIX="/home/pcurtis/.wine" wine "C:\\Program Files\\IrfanView\\i_view32.exe"
Type=Application
StartupWMClass=Wine
Icon=8ec2_i_view32.0

As you can see they are legacy applications from when I made the transition to Ubuntu with 6.06 and the .desktop files would have been created by an install by a wine version of about 3 years ago as the machine started life with 8.04.1 and I have /home on a separate partition which I preserve regardless of the type of upgrade.
