Cannot stop "Find in Files"

[szabgab]

On Windows using r12565 I tried to run "Find in Files". The first issue is that the Search Directory does not have a value and the search is done on - I think - the whole file system.
So it was running and running I did not see a way to stop it.
I tried to close the result window at the bottom with the [x]. It took a sec or so to react and then Padre crashed with this in the console:

Can't spawn "C:\strawberry\perl\bin\perl.exe": No error at dev.pl line 127.

This works properly now
