Wow – that’s a weird thing! Thanks for reporting this, Juaco.
I need a bit more info. What OS are you using? (Windows, Mac or Linux? Which version?) What kind of tablet? (brand, model?)
Does this happen constantly every time you launch Animation Paper?
Turning 180 – so your display image is up side down?
Please get back to me with more info – this makes it easier for us to fix the problem.
