LaggIng Issues

Hi, so basically I’ve been having some lagging issues in Toon Boom like every time i’ll try to draw with the pen from my Wacom Tablet is freezes then it return to normal function after an then I see the results. I’ve been trying to figure out what is going on and why is it doing this for the past 2 days. Any solution would help badly! I’m in an animation class and really need to figure this out any help will be appreciated.
