We have a Win Server 2008 R2 running a software package with an SQL Backend.
All clients run RDP to the server (terminal services) & they are all running the latest version of RDP.
If the software is used under RDP on systems running Windows XP & dual monitors, the parts list in the software takes minutes to update (and doesn’t display the list until all items have been rendered / updated). If we use it on just a single monitor on the same PC, the software works fine.
However, if the software is run under RDP on any other system, there is now issue & the list populates within 5 seconds. We have used it on WinXP systems with single screens OK, and on a vista PC running dual screens & it runs fine as well.
We have changed colour depth & resolution etc, with no luck. Any help would be appreciated.
