I've never had problems with PD 4 (also betas). 3540 run fine.
I have big problems with the latest "hotfix" 3810!!!
When resuming my XP VM it takes AGES for it to become responsive. I have uninstalled and reinstalled tools etc. The problem stays.
I have reverted to 3540 and it resumes as it always has and becomes responsive immediately.
I have filed a bug report already without getting an answer.
