#10 {Enhancement] Grey out "Run"

[Shash Chatterjee]

I spent quite a lot of time getting "null" in the Log
console (and a popup popping up and immediately
disappearing) when I selected a target and clicked on
"run". It appears that I needed to double-click to
mark the target with a checked icon before using "Run".

It'd be nice:

a) If the Run option was greyed out if there are no
targets "selected"
b) If a is not possible, at least some way of catching
the NullPointer exception and displaying a dialog that
stays up longer would help. Here's the NPE trace:

Good Idea. I'll add it to my list.

Thanks, Roscoe

New feature in release 2.2.8 - prints message to log console
when run action selected with no targets selected.
