>Recently I posted a problem with random calculation and printing bug in VFP8/9 with one of my inventory apps. It would give strange results about every tenth time for some customers. But never happened on any of my PCs.

>OK. I think I have resolved the problem. It has to do with VFP8/9 memory handling. One of my customers has two PC's: one with 384KB RAM memory (no problem) and the other with 1.25GB (YES random problems). The app has quite a bit of memory variables, public and private, and quite a bit of string handling and various complicated functions. Note that I never had any problems on my PC's - but none of my PCs have RAM over 1GB. It seems that VFP8/9 does not manage memory properly with PCs over 1GB. The same previous version of the app used VFP5 with no problems - could it was in the < 1GB memory era.

>My one 1GB PC had no problems and its VFP had about 0.75 available memory, so I put it at 1/2 GB max to be safe.
