This statement looks pretty innocent. But I had similar problems in the past with messagebox which didn't want to behave. It's extremely hard to identify the reason and find the workaround :( But the problem must go away. Did you try to reproduce? Could it show its ugly face only on slower PCs? Just trying to guess.

Yes. So, how about more visual effects?
