How to reset position?

[vnarod]

I had a cascading error and was getting message boxes with errors in a cascade mode, i.e. each one moved down and right from previous. I have fixed the error, but non ALL message boxes are shown in lower right corner instead of center. Reboot didnt help. How to reset it so that boxes are in the center again?

When you call MessageBox.Show, pass the form youre calling
to one of the overloaded methods (its the first parameter). That
way, the box will always show in the center of the form, Im fairly sure.

But it should be in the center by default! I am sure, somewhere in registry or somewhere else there is now an entry that makes it appear in the corner. But where???
