Wine apps unpinnable, do not match up with launchers

[AbuMaia]

If I try to add a .desktop launcher for a Wine app to Docky and then click it, when the window opens it adds a second icon for that app to Docky, instead of putting a light under the launcher. So far this has happened with boincview.exe, gsak.exe and utorrent.exe. I was asked to provide the output of " 'ps -ef | grep foo.exe' where foo.exe is the name of the wine executable ":

$> ps -ef | grep utorrent.exe
tardigrade 17379 17350 0 23:51 pts/2 00:00:00 grep --color=auto utorrent.exe

$> ps -ef | grep gsak.exe
tardigrade 17402 17350 0 23:52 pts/2 00:00:00 grep --color=auto gsak.exe

$> ps -ef | grep boincview.exe
tardigrade 17111 1 26 23:44 ? 00:02:11 /home/tardigrade/.wine/drive_c/Program Files/boincview/boincview.exe
tardigrade 17407 17350 0 23:52 pts/2 00:00:00 grep --color=auto boincview.exe

I have tried the instructions on the wiki page about customizing window matching by using StartupWMClass in the .desktop file, to no effect. The WMClass of each app is:

WM_CLASS(STRING) = "boincview.exe", "Wine"
WM_CLASS(STRING) = "gsak.exe", "Wine"
WM_CLASS(STRING) = "utorrent.exe", "Wine"

The .desktop launchers all look like this:

#!/usr/bin/env xdg-open

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Name[en_US]=BoincView
Exec="/home/tardigrade/.wine/drive_c/Program Files/boincview/boincview.exe"
Name=BoincView
Icon=/home/tardigrade/.local/share/icons/boincview.png

I'm running:
Docky 2.1.0, bzr docky r1659 ppa
Ubuntu 10.10
Wine 1.2.1

Changed the 3 launchers to now look like this:

#!/usr/bin/env xdg-open

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Name[en_US]=BoincView
Exec=env WINEPREFIX="/home/abumaia/.wine" wine "C:/Program Files/boincview/boincview.exe"
Name=BoincView
Icon=/home/abumaia/.local/share/icons/boincview.png
StartupWMClass=boincview.exe

Still not working properly. I then placed the launchers in ~/.local/share/applications, then click-dragged those to Docky. Again, still not working properly.
