------- Additional Comments From adrian.macneil@gmail.com 2006-28-05 04:29 ------- This still does not work in gnome with Wine 0.9.13, however I would like to point out that the new Linux version of Picasa (picasa.google.com) can do it. Seems odd that they can do it and we can't.
I ran the picasa version of wine taskmgr: WINEPREFIX="/home/user/.picasa" /opt/picasa/wine/bin/wine taskmgr
and it installed the systray icon perfectly in the gnome system tray.
Google provide a tarball of the exact wine source version they used for picasa.
The only explanation I can come to is that they way they do it isn't the Right Way to do it. If not, I hope this info helps someone.
