attach to process popover confusing

[themusicgod1]

To reproduce
1) start ddd
2) File->Attach to Process

popup comes up:
DDD: No Program
! Please open a program first. Ok Help

if you hit OK not only does *this* window disappear but also the window hidden behind it

DDD: Attach to Process
[PID TTY STAT ...

These two windows should not close when OK is hit on the first one, that is very confusing behaviour
