Task switching poser

I've been running the trial version of Dopus for a few hours and although I'm impressed with its potential I can't possibly stay with it because it takes over my PC. It prevents me switching between running programs using Alt-Tab (yes, I can go through the motions but Dopus always remains on top) or by clicking on the Taskbar. Neither does the Taskbar appear when I hover the screen pointer over it (I have it set to AutoHide).

I can't find any reference to this problem in this forum or in the FAQ, so I gather it must be my machine, but as it is almost new and has only recently been reconfigured with a fresh version of XP SP3 it should work with almost anything.

Any suggestions?
