Task bar doesn't disappear

I have an application with a form that has WindowState 2 (Maximized).
I have tested the application numerous times in the VB Environment, without any problems.
After creating a Setup Program for my application (with the Package & Deployment Wizard), I installed it.
The executable was running OK about half of the time, but sometimes the Task Bar just would not disappear.

???????

A maximized window covers the space on the desktop, but not the taskbar (at least it's not supposed to...)(and other toolbars like the office toolbar), so it's correct behaviour... only weird it works sometimes...
