I've had to uninstall all Transparency software to get the Taskbar Preview in WindowFX to function correctly; if used long enough with other transparency software, even with its own explorer window transparency feature, it will cause minimized windows to be invisible when you maximize or restore them.
I'm using WindowFX 3.0 (32-bit)
I have XP Pro
ATI Radeon X1900 XTX with latest Catalyst drivers.
Any help or fixes for this would be dearly appreciated - thanks in advance:)
