V1.2.0 Won't slice

I've been having issues with Slic3r for the past few months. Crashes, extremely slow slices (and yes, I have avoid crossing perimeters turned off). I have 1.2.0 and I ask it to slice a simple car holder and it does nothing. I press the export G-code, it asks where to put it and it just sits there. I don't get green bar or anything. If I press "export G-code" again, it tells me that it is working on an export job. Running a MBP with 16GB memory and SSD drive. I have 8 threads enabled thinking that would help. Under activity monitor it says that Slic3r isn't using hardle any resources.

I like the all the features, but Slic3r is like a pretty girl with all the right stuff that never puts out, literally.

Do I have a bad install? Should I go to 1.1.7? Can I just download that one and install it or do I have to uninstall this 1.2.0 first?

Holy Oddness Batman. So I started mucking around and went back to the -default- settings that I haven't used in year. With those it sliced perfectly. I started adding back in the three different config files that caused the crash. Narrowed it down to the 'Print Settings'. I started changing the values back to default and running the slice. Crash, close, re-open and change a couple more.

It is when the 'Skirt' value is set to "0" instead of the default "1"? I want manly prints with out skirts!!! I don't even know what it is. I'm already doing two loops. Is a skirt touching the part like a mini-brim?

So I changed it back and forth three times and that is the value causing the hang-up????

The loops ARE the skirt

I'm surprised that they let you select zero if loops is greater than one.

If you say no loops but skirt 1 layer, I don't think it freaks out, actually that is how it says to turn it off. Seems like it should be the other way around. Do you want a skirt and how tall, oh, by the way, how many loops do you want it to be thick.
