Ok, it caused a problem after all. See:
 http://bugs.freepascal.org/view.php?id=31496
The freezing loop must be solved some other way, or maybe the
ButtonPanel layout could be fixed some other way, don't know.

 "VTV itself is rather old version (last commit from May 17 2015)"
There are at least 2 maintained main versions of VTV now, versions 4 and 5.
Could you please update your VTV and test again.
If the problem continues then we need a demo application attached to
the bug report to reproduce the error.
Then somebody, maybe Jesus Reyes, can try to fix it in VTV code.

Any ideas are welcome.
