EVDRE problems after upgrade to win7

Hi,

One of my customers is in the middle of an upgrade from win XP / Office2003 to Win7 / Office2010.

On some of the upgraded PC's we experience problems running several reports (EVDRE reports). From the user end the screen freeze and if I look in SM50 the process is no longer executing.

The problem does not occur on all upgraded PCs and on the troubled PCs not every time. I have tried to look for a pattern and the only one I have found so far is that the problem only occur when I execute large reports.

I have tried to look for a timeout function in Win7, but haven't found any.

On the old PCs running XP we do not experience any problems at all.

The customer is running 7.5NW SP05 patch2.

Any suggestions?
