trueSpace message windows hidden behind the program?

I ran into this recently, with Caligari trueSpace 4.3 acting like it was always on top, no matter what, even on top of its own "Load scene" and "Load object" windows, or any error messages, to name a few (this would also make it appear to be frozen). It was annoying, because you couldn't load or save anything (unless one worked blind, using the esc and enter keys, for example). This is under Windows XP Pro. I did some searching and it turns out this occurs if the Windows XP Taskbar is set to Auto-Hide. If you disable auto-hide on the taskbar, trueSpace behaves correctly.
