I added in the debugging you suggested, it looks like the XawTextReplace
call is failing.. the second of your scenarios.
The mainlog tail text-box appears to be behaving strangely too. The window
scrolls to the far right of the horizontal scroll. I didn't bring it up
before as it seemed a bit picky, but now it might add further weight to
there being some discrepancy with the X libraries.
I've got XFree86-4.0.3 and Xaw3d-1.5.
Matt.
