Unfortunately, running multiple commands concurrently in the same
mapset is potentially unsafe. Most of the time you will get away with
it, sometimes you won't.

You can prevent the Run button from being disabled by removing or
commenting-out the following line in etc/gui.tcl:

	catch {$opt($dlg,run_button) configure -state disabled}

However, I'm not sure whether the GUI will cope with multiple
concurrent invocations (the earlier GUIs weren't designed to handle
this case; it just happened to work).
