Program Freeze and fatal error in Sketch

[cad-neophyte]

I have just started using Freecad and think the tutorials are good! I followed the Bike Rim tutorial and mimicked almost every click, deletion and constraint as I could. During the first video if two when the designer would come to the making the left two lines parallel, the program would freeze and then a "report error" window would appear. Once clinking my choice the program would close.

This only happens while using the "parallel" button while in Sketch.

I was successful in saving the project one my third attempt right before reaching the error point. I would restart Freecad and try again. I had to finally reboot my computer and reopen Freecad. Once I did this, I was able to make the first set of lines parallel and the second set. When I tried to do the third set of lines, the error happened again.

System: Windows XP PRO, 32bit
