Two technical problems I'm having with Kagetsu Tohya

[KuriGohanandKamehameha]

1. Every time I open the "CD" folder in the game files, my window freezes, and weird things start happening when I play the game

2. Every time I exit full screen mode (pressing F) while running the game, it automatically exits full screen on other windows that are currently open in full screen. (Only started happening after I opened the CD folder)

I had opened the CD folder once before this, and that time a weird glitch happened where some of my desktop icons disappeared. That was fixed by restarting my laptop. This time restarting didn't fix the problem.

Anyone know how to fix this? Thanks (specifically the minimizing issue)
