Look at the following pictures for 3.0.103 under Vista SP1 4GB. The Titlebar buttons disappear when the window is maximized.

This actually a lot weirder than I thought. The buttons disappear only on the primary monitor, not from the secondary monitor. They disappear if I move or drag the window from the secondary to the primary, or if I maximize any window so it maximizes on the primary. The buttons display properly on the secondary. I am copying the end of the log (showing an error) and the troubleshooting info below. The primary is a 12" Tablet PC (Lenovo X61T) and the secondary is a DELL 24". The graphics are Intel 965.
