First, let me apologize for the lateness of my response.
We have not run any Foxpro for Windows 2.6 applications on TS. My mention of Microsoft cautioning running such applications on TS was that they eat up processor capacity. My guess is that the main problem lies with the processor availibility and any other issues are related to that.
Issues with disk caching refer to running VFP 5.0 thru VFP 7.0 applications in a standard network scenario. We were advised to turn off disk caching by tech support people with commercial VFP Application when we encountered similar table issues with their software at our client's site.
I am sorry that I do not have any other information that might be helpful.
Again, apologies for the late response.
