Hi,
	I am trying to write a program entirely in Xlib ( for
	performance reasons ), I am borrowing some code from a program
	that I wrote last year ( which I am pretty sure worked ), but
	when I run the program, I get the following error from Xlib:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  62 (X_CopyArea)
  Serial number of failed request:  73
  Current serial number in output stream:  150
Exit 1

	How do I track down EXACTLY what is going wrong, it seems that
	when XCopyArea is called, it returns with an OK status, and
	its only when the event requests are processed that the
	message is printed. Any advice would be gladly appreciated!

thanks in advance
