Shared Profiles Tools nonfunctioning after Resuming VM from Suspended State

I have noticed that Shared Profiles Tools no longer works after I resume my VM from a suspended state. From VM, I couldn't access documents that are placed in the Documents Folder of the host OS. This is happening consistently. It seems the only way to workaround this is to completely restart the VM.

I used the Suspend feature a lot in PD3 (by simply closing the window), very convenient as I get the VM up and running quickly instead of having to restart. Is this a known issue and is there a resolution?
