Sorry about prior message. Looks like I lost somehow several words and characters thru the text. (I really don't know how it happend)
Here is the corrected text:

---------
If modal form has lost focus, it dies (becomes unavailable).

It can happens if some another thread (OnTimer or on OCX Event) contain SetFocus() call.

Does somebody know how to solve the problem?

PS. "Remove all SetFocus() from the project" is not an answer :-)
