Greetings Vlad

Thanks for replying. Thought nobody had any ideas on the problem.

>> If your code making a lot of updates to the visual controls,

if anything, slightly fewer in the problem situation than in other scenarios where it works with no hassle.

>> Widnows Events Queue for your application (for VFP) may be corrupted or contains so much events that they don't work properly. This is the main cause of many >>refreshing problems. And this very depends on available memory, application code, Windows version etc etc.

I'm sure this is NOT a refresh problem. Its almost as though it is running the query with no cache and thus takes a few extra seconds to display the results.(But that, presumably, wouldn't be fixed by simply stuffing the keyboard before a wait command - which is all I've done to get around the problem pending a correct solution)

>>To solve this problem, just put DOEVENTS command

did that, just in case... No effect.

>> Finally, you may try to use _VFP.AutoYield setting to allow events processing between VFP commands,

hadn't come across that one before, so thanks for that. But turns out that it was already set to True.

Guess I'll just have to accept the bodge for now.

Ciao
