Okay, so I have used this many times before but I cannot figure out how to fix this. This is what happened. after i open up any type of document like an actionscript 3.0 document or anything, if i draw with the paint brush as soon as i let go of the mouse button the line disappears. If i go into the timeline and click on the frame it shows up again, but if i draw again it disappears and i have to click on the frame to see it. Is there any way to fix this??
