I've been using Player 5 for few days now after upgrading from Player 3 and have noticed some really strange behavior and some blatant bugs, perhaps some of you can shed a light or confirm that you are experiencing same issues. My box is a bit oldish, host xp64 with few guests xp32, but so far everything was working ok - at least Player 3 was not complaining.
Issues I have, or have had so far with player 5:
- extreme time skew in virtual machines after they have been working for over 12 hours. I do have AMD processor, but Cool'n'quiet has been disabled in BIOS, so MS Support article 895980 about QueryPerformanceCounter should not count. Player 3 did not have such issues. Quasi-solved by disallowing VMWare Tools to adjust VM time to host time and using Internet time. This situation had lead to...
- stopping of VMWare Tools services in 2 VMs, leaving them in such a state that they would not restart. Fixed through reboot of host 
.
- lost keyboard control / GUI control to switch from one VM machine to another directly (Ctrl-Alt-LeftArrow or Ctrl-Alt-RightArrow). Since there is no GUI segment that controls this as there was in earlier versions, I can only assume that this had been removed on purpose - can anyone confirm? Really VMWare?
- spike in CPU usage from ~15% to 50% if CPU on host is busy otherwise (for instance, I was opening a 30MB binary firmware file in Notepad) - and vmware-vmx.exe would happily take half of all time on cpu while notepad was taking the other half? Out of 6GB physical RAM, only 2,5 were used with VM's up, binary file was on completely other physical disk...
- VM's are still not liking dual monitors, especially so when running in fullscreen.
Had anyone else experience these or similar phenomenons?
