Can't draw with touchscreen?

[mpsmith]

Hi! So I made one song as a guest on here before, using a touchscreen laptop. I registered today, and now i can't draw using my finger on my touchscreen? I can still scroll, press pretty much any button in the site using touchscreen, yet can't draw notes. Obviously this isn't urgent or anything, as I can use the mouse, just a bit annoying. Anyone else have this?
