Thanks for that. I suppose I should have said in my original message that I know I can position it using the very long winded geometry method of working out the screen size, then the window size, etc.

It's just so annoying that I can use Popup with no parameters to get the main window in the centre of the screen, but once I've issued a minsize command, it all goes wrong.

Spike.
