>So the bug is fixed in VFP8. If you run it under VFP6 or 7 you will see that I'm talking about.

There's absolutely no bug in there. What I have in VFP 8 is exactly the same as your both versions. This is normal. It is normal it reacts this way.

>Tricky and it's a direct way to make more bugs. I wrote how I fix it before. It was a dirty solution, but looks like no right way in this situation.

There are needs to use a specific set of tools when they are required. In this situation, the use of modal window, IMHO, doesn't apply. This is why you are facing those situations. Just go back to the base points such as I described along this thread.
