Does anybody fix this problem?

Here is my quick dirty change for XDarwin 1.1 (XFree86 4.2) with OS X
10.1.5.

One Question:
This patch looks fine except 'sam'.
When I start sam with short file, no text or pop up menu appers.
If I start sam with longer than screen length text, there is no problems.
