And here’s the reason and the solution to the problem!
All to do with ‘Font smooting’….
I have been remoting to the Controller and the generators with this option unset.
Win2008 terminal servers are set by default to have font smoothing enabled.
So.. I have to remote to the Controller with font smoothing enabled:-

I have finally resolved the cause of this issue!!!!
Having gone through the process of detailing the problem below with the various tests, I have been able to conclude that the issue is a bitmap sync problem whereby the synchronisations appear differently if the Generator window is open or when it is closed. Since the bitmap synchronisations are recorded in VUGen the accepted syncs will only appear correct if the Load generator window is open. If it is closed, the terminal servers display with a slightly different font!!!! Thus the scripts have been failing at the initialisation stage when the successful logging in offers the main application window and checks this with a bitmap sync. – Allowing for either of the bitmaps to be accepted allows the script to continue whether the generator window is open or closed – however every bitmap sync thereafter will fail.
The in 2003 terminal servers do not have this issue!!
So the problem appears to be with the 2008 terminal servers offering different display options - I will chase this up with our citrix experts but if you have any thoughts on this it would be much appreciated!!
