iMac display freezes unpredictable when using Parallels 7

[JulianW]

Hey guys,

I have a problem running the Parallels testversion on my iMac (27", 2,7 GHz, 16GB, Lion 10.7.3, all updates installed).

The display freezes sporadical (every 2-5 minutes) when I´m running Parallels (with or without running VM, no difference). Win XP as VM runs without problems (until freezing appears).
I can only move the mouse-courser but Lion and VM do not react.

Only working action: pressing cmd+alt+esc on keyboard. Nothing more! I don´t have to quite a programm, they all run fine, just the display freezes.

I already reinstalled the software two times, no change.


I really would like to go on with Parallels, but I´m pretty stumped now, so it would be great if anybody can give me a clue,
Thanks in advance!!


PS: On my MacBook Pro (also Lion) Parallels is working fine without problems.

We need to investigate the issue as it sounds unfamiliar for me. Submit a support request at www.parallels.com/support - it is free.

Thanks for your quick reply,
I tried sending a support request but I have some problems getting the Support Code - at my account there is no code shown ("not available") although I activated it via the software interface which was acknowledged.
Activating via the browser had no sucess.

Is it possible to activate test versions at all?
