OK, with some tweaking the wait box and your code suggestion runs fine - however there seems to be an issue with Tk::WaitBox and it's "cancel" button feature - ie, the button displays, but it's unclickable - the mouse cursor sits on an hourglass when it's over the box, can't click anything.

I've been trying to create my own wait box, but for some reason I'm running into a similar problem I had before - except this time it seems to be bypassing the "connect" sub completely and just displays my wait box.

further suggestions appreciated.

Thanks,

Glenn
