This problem has been resolved.
I got onto the System Administrator and asked him to give admin rights to the user that was having the problem, ans that sorted the problem out
I dont understand though how 'Securtiy Rights' would cause a problem running 3 lines of code (only from a .prg)
Does a Wait Window look to update someting in a folder (Temp folder perhaps ??) if running from a .prg , and why do other commands not cause a problem ?

Gerard


>>Hi Al.

On the PC, rendering via RDP is different than it would be if drawn directly by VFP running locally, so that test does not rule out a bad video driver on the PC.

>>Also, the error refers to where the Temporry files are located on the C drive, so I am wondering would it be some sort of securtiy thing, although I changed the Tmpfiles folder on Config.fpw to point to C:\ and this did not fix the problem (Checked that the same user could read/write files to the c:\ folder first)

>If you have multiple users/sessions running your VFP app simultaneously on a TS, you may have to be careful to give each of them a separate folder for their temp files. I believe you can do this by using their "User" folder (or a subfolder of that). If a lot of users share the same temp files folder there's the chance they could step on each other's temp files, with unpredictable results.
