is there a way to suspend single thread using debugger ?

Hello,

is there way to tell debugger to suspend single thread in my multi-threaded
program ? I can see all my threads displayed in “Debug” view, but if I
highlight one of them and click “Suspend”, all threads get suspended.
What I would like to do, is to suspend only the thread that I am interested
in at the moment, and keep all the other threads running. Would that be
possible with Momentics 6.2.1/gdb ?

Thanks in advance,
Andray
