Hi Peer,

That's a bug in that script, it should disable the repeat checkbox which is done by setting:
// config: norepeat
at the top of the .js script file. I've updated the script to have that now so you shouldn't run into this with the updated version.

The repeat checkbox is primarily meant for use with drawing commands and not ones that do selection.

You can still repeat a command that does selection by right clicking in the viewport or pushing the Enter key while in selection mode. If you only need to repeat things sometimes it's easier to use to use right click to do it, the repeat checkbox is for stuff like you're going to draw a whole bunch of points or lines.

Sorry you ran into this data loss. If you run into this kind of loop again you can recover your file by triggering a crash.
To do that find the pid for the MoI process in Activity Monitor and from a Terminal prompt do:

kill -s SIGSEGV pid_number_here

That should cause MoI to trigger the crash dialog where you can save your file.

I'll take a look at this part in a bit.
