doh! That fixed it, but you were right (as always), it didnt do what I 
was expecting (or maybe just hoping :) )

So, on to the WM_PRINT event method. If I cant do:

	$tempwin->GetDC();

because its a scalar, and

	Win32::GUI:GetDC($tempwin);

doesnt seem to be able to find GetDC in the Win32::GUI package, how can 
I find the DC for the scalar $tempwin entry? (I picked a bad week to 
give up smoking AND caffeine)
