Hi again, everyone!

Last week, I posted asking for help with a problem that I was having with
XCopyArea(). 1) it's too slow,  and 2) it hogs the server.  I recieved a
few responses, and here's what's what:

The simple problem of the mouse clicks not registering was solved by adding
an XSync() call... I am embarrased to admit that I didn't put one in in the
first place, and more embarassed that I didn't notice this when the problem
manifested itself.  Insert red face here.  Oh, well, when I get to be a
notorious X programmer, these things will cease to escape me.

As for the speed that the program runs at _after_ I added the XSync() call, I
received one suggestion to buy a hardware accellerator, which should speed
XCopyArea() (among other things) up noticeably.

Barring that, I'll have to roll my own copy routine.

It seems (by the mail I received on this) that there were one or two posted
replies to my question, which unfortunately didn't make it through. If
you posted a reply to the net, and you saved it, could you be so kind as
to send me a copy?  I'd really appreciate it. 

Anyway, thanks for your help.
