Paradox on Remote App Server / Remote Desktop

I have installed Paradox 11 Runtime 11.0.0.233 (from X3) on a Windows 2008 R2 Server, and set it up to be accessed via Remote desktop or as a Remote app.  The application is not happy with this environment and I need to try to sort out which factors are causing the problems.

Previously I had this application set up on a Windows 2003 server using Paradox 8, with users accessing via Remote Desktop and everything was fine.

Upon switching to the new environment, however, I'm getting:

* General Protection Violations

* Extra pages when printing one-page reports

* Table repair utility does not recognize Paradox tables

I understand that there are/were issues with Paradox 11 and Vista.  Since Windows Server 2008 is "vista-like" I wonder if some of my issues could be related to that.  Are the known paradox-vista problems documented somewhere so that I can review them?  Also, I've purchased corel Pro X5 - I know there is a later version of Paradox included - I'm hoping the runtime is also a later release.  Could the solution be as simple as upgrading?

Also, if anyone has done a similar setup and has any suggestions for creating an environment that paradox will file acceptable, I'd appreciate any insights you might have.
