"Debugging Helper Missing" dialog not on top

Steps to reproduce:

• create a simple Non-Qt project (C or C++)
• set a break point on int main(void)
• set to run in debug mode, press Debug

Current behaviour:

• Creator brings up the qtcreator_process_stub window which makes Creator losing the focus and the messagebox "Debugging Helper Missing" will be displayed behind Creator (so you only see that debugging does not continue)
• if you click on the titlebar of Creator you'll get the dialog on top and everything is fine

Expected behaviour:

• no matter if Creator would bring up another window or not, the message box should be displayed on top
