can't see lines while drawing?

:’( hi, just bought toon boom animate and i can’t see a line as i draw one. The line appears when i let go of the mouse button but i can’t realistically make a good animation with this :frowning: i’ve been scouring the net and found that this can be a graphics card problem with OpenGL but i can’t see an option to change the renderer in prefences? it’s not my computer cause it’s pretty powerful. any help would be great thanks.;action=display;threadid=2994;start=msg14517#msg14517
