Here is an embarassing question, with a bit of background.

First the details:
 Sparcstation, color, server (patch 1-8, purdue).

I create a bitmap 'a' using XCreateBitmapFromData. It's associated drawable
is the RootWindow.

Later, I create a Pixmap 'b' with associated drawable RootWindow.
(Using XCreatePixmap)

When I call XCopyPlane, using 'a' as the source and 'b' as the
destination, the call fails with a BadMatch error.

Is there a way in which I may discover the "root" for both of these
*maps?  Are there other methods of generating this error, that are
undocumented and easy for the unknowing to do?

Many Advanced Thanks,
Vince Kraemer
