Execution Window

[Mark Hinton]

When I select View - Execution WIndow, and then Run DDD on my program, I 
immediately receive an error message in the gdb interaction pane. The gdb 
interaction looks like this:
        (gdb) run
        Starting program: a.out
        putpkt: write failed: Input/output error.
        (gdb)
I'm running GNU DDD 3.2.1 (x86-pc-nto-qnx)
I suspect I've missed something in the GDB settings or in Preferences. Any 
feedback or suggestions welcomed!

Thanks,
Mark
