Ok, I think we misunderstand us. :-)

Our Customer has had our Programm in FPW2.6 Version since a view years. We have programmed a (completly) new Version in VFP6/7. Now he got the new Version, and the problems.
He isn't the only Customer who has this Version. So we are looking for optimiziations specific for Citrix Metaframe. Because:
>>VFP7 needs more resources than FPW2.6. And our APP has become more complex. So for the User on the same machine, it seems to be slow. But it's on Citrix more slow than on a "normal" Windows.

>>>Switching from VFP 6 to VFP 7 is not the problem. If anything, expect VFP 7 to be better under Citrix. Obviously updating from VFP 6 to VFP 7 did not capture all the nuances of the VFP 6 environment. That's the first place I would look. Check the contents of SYS(2019), config.fpw, for both environments, for example.
