If you can get me a quick sample to reproduce your problem I will see if I can get you a fix.
Edhy,
I think that your run-time problems are totally unrelated to this. I have reproduced your problems and given you several options to fix the problem. This is not the same issue.
I am having the same issue, but not only at design time, but when running the .EXE out of VS IDE.
Please check this thread to see if anything applies to your particular issues:
