The long-standing (since AIX 4.3.0 came out in late 1997) problem with Xt wedges seems to be fixed. X11.base.lib.4.3.2.5 is the fix level required. Minimal testing shows that: a) 'xemacs -nw' no longer spins chewing CPU. b) --with-dragndrop=no doesn't seem to be required - I suspect library indigestion with IBM's Motif/CDE libs calling MIT X11R6.4 Xt and X11 libs. I need to be doing more testing on (b) to make sure all of that is clean now. I will be sending a patch for the PROBLEMS file to xemacs-patches shortly. /Valdis APAR NUMBER: <IX89470> RESOLVED AS: PROGRAM ERROR ABSTRACT: <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT ORIGINATING DETAILS: Applications may malfunction when using XtAppAddInput with XtInputExceptMask. LOCAL FIX AS REPORTED BY ORIGINATOR: RESPONDER SUMMARY: Applications using XtAppAddInput with XtInputExceptMask can generate exception callbacks even when there is no execption. Also, applications can hang intermitently when processing alternate input when using XtAppProcessEvent. RESPONDER CONCLUSION: Fix a macro in libXt's POLL code. Fix hang in XtAppProcessEvent.
