I have confirmed that this is a compatibility issue with Windows Vista caused by two separate issues.
For some reason Windows Vista doesn't like 2 color icons for tray icons anymore. The blank icon was increased to 16 colors and the problem was resolved. The taskbar caption blinking that was caused by another issue and that too has been resolved.
These changes will appear in 3.6 RC2.
