The Drawing lines disappear ?.

Hello,

If I draw (in drawing mode) using the brush tool I can do two or three strokes, and then if I do a fourth stroke the second and third strokes just disappear. I have no idea why it’s started doing this!

I started new projects shut down toomboom harmony and opened it again. It’s driving me crazy I have n idea what to do.

I’m new to harmony so I may be doing something wrong.

thanks
