Also I wish I could use my cintiq with a second screen but as soon as I use both any and all drawing programs either eat shit with pressure or throw the cursor five years away from where the pen actually is. No idea why it does this and can’t find a fix. gdi.

If you’re using windows 8 the cursor thing is probably display scaling:  you may either have to turn off Display scaling in the display options or “Disable display scaling on high DPI settings.” in the app properties page.
