I can scroll around all I want, but if I click on one to finger wserver , close that window and scroll in the list of wx alerts for a little bit xastir ends with a seg fault. nothing unusual in the term I started it from except the "segmentation fault".I am running on opensuse 10.2 and have almost everything compiled in.

Just began to look into those segfaults tonight.  I can reliably crash 
xastir (built with lesstif) by repeatedly opening the send-message dialog
and changing the format between d700/hamhud/d7, then closing the dialog.

The segfault is in a free, down several layers of motif calls.

Perhaps it would be best not to try the on-the-fly changing of the dialog,
since clearly lesstif has some serious Issues with that?  How many dialogs
do things this way as opposed to the close-dialog, change, redisplay method?
