response from Paralles
To update, I recevied an email from Parallels Customer Service a few minutes ago. The contents are as follows:
"Unfortunately this is a very common issue and we still can't fix it.
Please try to visit our forum and wait until the issue will be
resolved."
I am really surprised this bug made it out of beta testing as it could be easily predicted that a large number of users would be upgrading from 3214 to 4128. If the issue is common, this suggests a lapse in QA/QC. I'm also surprised there isn't an announcement or more on the forum from the the Parallels team, just user posts at this moment.
