Every time I use this tool it fails to complete the closed line I'm trying to draw. It continually stops in the middle of me drawing a line and closes off whatever it stops at after I remove the pen from the wacom tablet. This is making even simple selections painful to accomplish.
I have restarted the program mulitple times and it doesn't help. When it happens I have no more than 500 megs of RAM being used by the program so it's definitely not a lack of RAM. I have also done all the setting changes suggested (multicore = 1, scratch drive chosen, undo levels = 40, memory usage = 80%) by people with no effect on the tool.
Please look into this tool because it is definitely giving me issues!
Edit: Something I also am noticing is that most of the time I will see the screen flicker for a split second right before it starts ignoring the line I am still drawing, I really do believe this is some kind of bug.
