It really does sound as though there is a nasty interaction between OA tasking and HP-UX's select() (or poll(), depends what they have in the innards of XtAppMainLoop()). Tasking is quite likely to use signals, perhaps they're interfering .. It won't help you much to know that we've not seen this problem with Verdix/Solaris, DEC Ada/OSF1.3, GNAT/Solaris, GNAT/Linux :-) Do Aonix have a view? Is there a GNAT port for your machine (would be useful just as a comparison point). -- Simon Wright Work Email: simon.j.wright@amsjv.com Alenia Marconi Systems Voice: +44(0)23-9270-1778 Integrated Systems Division FAX: +44(0)23-9270-1800
