4.005 won't run on Vista Business - Microstudio 4.006 fixes problem

[norrodb]

Hi !

I searched the forum, but did not find this issue.

I just purchased and installed 4.005 on my laptop running

Vista Business
2GHz Duo
2GB ram
ATI Mobility Radeon x2300 with 64 dedicated RAM, 800+MBram available
DIrectX10

Microstudio installed with out issues, but when I launch it, it never comes up on my desktop. I can see the process running at about 45% cpu, but never shows.

EDIT: to add, the task does not show in applications list, but only in processes.

I have .Net Framework 2.0 and ran windows updates.

I am now at a road block on what to try next.

Any ideas?

Thanks !
Brent
