Bad thing to my computer...

This program is freeware.
Neither Studio Pixel nor Aeon Genesis is responsible if it does Bad Things to your computer.
(Of course, it shouldn't, but that's beside the point.)

Unfortunately it did. It made my mouse cursor interact out of alignment in Microsoft Paint after playing Cave Story in fullscreen. This happens if I have a mouse and a touchscreen monitor (while both enabled). Paints correctly with touchscreen, but way out of alignment with the mouse. OS is Windows 7 I am using. Desktop resolution is set at 1920x1080.

 

Does restarting your computer do anything?
Random stuff like this might happen with OS virtualization, but I've never seen it with a primary OS.

If the touchscreen is not enabled, what happens?

 

I can't find the particular device to disable the touchscreen in Device Manager but I can unplug its USB cable on the back of the monitor to fix the problem.

Everything returns to proper alignment with the mouse interaction on paint. Even after running Cave Story.

Restarting, or logging off and back on fixes that too. Same goes with another program running on Fullscreen.

This is not virtualization, this is primary.
