Display problems on resuming from Mac Sleep

I'm having regular problems with display on a resume from sleep since the P12 'upgrade'. The VM display goes down to 640x480 mode and occasionally resizes back to 'normal' for the MBP Retina (except all the windows are now in the top left corner of the screen) but I usually have to 'restart' the VM. Occasionally I have to restart Parallels itself. I lodged a ticket a while back but didn't hear back. I've also still got the 'broken multiple screens' problem mentioned in other threads.

 

Please try reinstalling Parallels Tools steps followed.

 

Thanks for that - I've been a user since P9 - Reinstall tools is something I do one regular basis. I've uninstalled P12 according to the FAQ, repaired permissions through Disk Utility, Reinstalled P12 according to the FAQ, re-installed P tools a couple of times for the hell of it and well what do we know ? I still have the problem. Still have the broken multiple monitors problem as well. Plus my Outlook profile has been corrupted 3 times now. Good job I keep backups. Love this Alpha testing lark - I think I might pay for it.... Oh wait...

I'm reduced to:
1. Running Caffeine to stop the Mac Sleeping throughout the work-day
2. If I do want to move the MBP I shutdown the VM and re-start - just like we used to in the old days.

Maybe I've got high expectations but P11 was stable. Worked with Windoze 10 , worked with multiple monitors and worked with Mac sleep and probably more importantly didn't corrupt my Outlook profile. Can you remind me what I paid you money for my "upgrade" guys ?
