Starmoney8: only visible when Internet Explorer is running

Hello,

I habe a problem with Starmoney 8 on Parallels.
When I start Starmoney, the Symbol appears on the bar, but no windows appears.

I found out, that, when I start the Internet Explorer, and change to Starmoney, Starmoney is visible on the same window-size as the Internet Explorer is.
That means, when IE is running in fullscreen, Starmoney is visible in Fullscreen.
When IE is in windowed mode, Starmoney is in windowed mode.
When IE is not running, Starmoney is not visible.

Does anybody know this problem and can help me to solve it?

Thank you in advance!
