Windows 7 highly unstable in Parallels

Hi all

I am still fairly new to Macs and to Parallels. I had Win7 release candidate installed as a virtual machine only, and a WinXP bootcamp partition that I enabled through parallels. Everything worked great. Got my Win7 discs in the mail last week. Removed all existing Windows installs and VMs. Created a boot camp partition for Win7 (50GB) and loaded Win7 no problems.

Began using it in Parallels and it is highly unstable. It frequently hangs, and applications and OS become unresponsive. Cant' click or type anything, can't reboot. Have to do a 'hard' VM reset and Win7 reboots (taking forever to do diskcheck).

Any ideas? I'm on a macbook pro, latest model, 2.53 GHz C2D. 4 GB of RAM with 2 allocated to Win7. Plenty of harddrive space on the partition. 128 Video Ram allocated. Both processor cores enabled. Hypervisor turned off or on doesn't make a difference.
 
Let me add I have the latest updates to Snow Leopard, Parallels and Windows. Windows install is 64-bit Ultimate edition.
 
I have the same setup except for running on a Mac Pro. My setup is also unstable (and that is being kind).

Things that have crashed or hung up since my installation:

MS Word, Powerpoint
Windows Media Player
Firefox
Webex Meeting Manager
Parallels Internet Security Powered by Kaspersky
Windows itself

I installed from scratch with a new version of Parallels 5.0, Windows 7 Ultimate 64 bit onto a newly installed drive.

Any suggestions would be appreciated.

Here are some of my settings:

Processors: 1
Main Memory: 2048 MB
Network Adapter: Bridged - Default Adapter
Set the total memory allocated to PD: Automatically

Mac Pro early 2009 quad core
Mac OS 10.6.2
12GB Ram
PD 5.0.9200

Thanks
 
Well... I was eligible for the upgrade to 5.0 which came out just a few days after my post. When I upgraded, huge improvement. Windows has not crashed on me yet.
 
Are you running Win 7 in 32 bit mode? If not, perhaps that will fix your problem. I have a friend who is running Win 7 in 64 bit mode and has trouble with some programs.
