>>It's unknown what the real scope of this problem is. So far it seems to be directly related to changing pages in a pageframe when you have lots of forms and objects in memory. So apps that by their nature don't do this probably won't be affected. Our application is definitely very large and very complex, probably one of the largest commercially shipping applications written in VFP. We're definitely affected by it, to the extent that we will not be able to ship under VFP 6 until the problem is fixed. Small apps will probably not exhibit any noticeable slowdown.

We have people running Windows 95 and Windows NT. The problem in 5.0a happens considerably less under NT than it does under 95, but telling our clients to switch to NT would fly about as well as a large elephant flapping it's ears.

The slowdown problem in 6.0 happens under NT and Win 9x - platform doesn't appear to make a difference.
