Patch for error when double-clicking on process in attach dialog

Patch for error when double-clicking on process in attach dialog

[James Ingham]

Hi, all...

I just checked in the following patch that fixes an error which would
arise if you double-clicked on a process in the Attach dialog if you
had not previously loaded the executable for the process.
