interupt execution in gdb

Hi,

usually I use STRG-C to stop exetution of the programm I debug. But when I start gdb directly from PhAB STRG-C closes the whole gdb.

Furthermore there is a lot of output produced by gdb:
[tcsetpgrp failed in terminal_inferior: Inappropriate I/O control operation]
this line repeats very often…

Is there a way that gdb behaves “normal” when started directly from PhAB??

It’s QNX 6.3, PhAB 2.03, gdb 5.2.1.

THX in advanced,

Smee
