I had sent a message to tell you about my experience, but I couldn't found on this site. I thought the message might be lost. Let me repeat the message. If you received the message before and you thought it was useless, you could ignore it.

I had the same experience, however, it was long time ago. I forgot the details. I only can do my best.

First of all, don't use your common sense. I think the problem is caused by VFP bug. If you always use your common sense, you never know what's going on. In my memory (actually I'm not sure), I always set the tab index of the destiniation control to 1. For example, the original sequence is A B C D. When the user select B, you set the tab index to B=1, C=2, D=3, A=4. When the user select D, you set the tab index to D=1, A=2, B=3, C=4 and so on. The method looks very stupid but you can try. If it wouldn't work, you could use my idea to find the solution.

Wish you understand my message. You are always welcome if you still have same problem.
