This is excellent news to me. I can get a faster machine (processor/video card/more memory) to handle the slow down with GUI stuff. And also, any speed problems with the GUI are easily identified (ie. you notice them easily) while data retrieval/manuipulation slowdowns are not so apparent. That is half the battle sometimes (identifying what could use some tweaking).

Take care,
Joe

>>I don't think we should be upset by this fact (6 is slower than 5 for some operations). This is typical with any computer program. As programs become more complicated (powerful), they demand more processing power and more memory. Generally, performance of older software is better than newer software on non-state-of-the-art machines. But, more powerful machines should run the new software at similar speeds.

>>>FoxPro has always gotten it's speed from doing things in memory vs. on disk. If you don't have sufficent memory, then the OS provides "virtual memory" with is really just mapped to disk. It appears that VFP 6.0 requires a larger amount of memory to do somethings, and I'm assuming they have added more overhead to some functions to provide more features and better integrity / error handling. (At least that's my story and I'm sticking to it <g>.)
