i have a sales invoice entry form, when 2 users enter data in same time.
user1 entered 5 products in grid and user2 entered 3 records in grid

when user1 save the buffered data first, it is displyed in grid of user2 with his buffered data.

OR

when user2 save the buffered data first, it is displyed in grid of user1 with his buffered data.

can i solve this problem with sys() commands.

below linking showing this is a bug in vfp9.

> Second because VFP 3.0/5.0/6.0 was originally written to work under Windows 9x OSs and its internal memory manager Doesn't Play Well with NT-based OSs. The SYS 3050 hack can help under certain circumstances. It doesn't help if your client doesn't have much memory to begin with. It doesn't help if (for some odd reason) you're still using a windows 9x OS - and can actually reduce performance in rare cases.
