Does this happen in the very first screen? I'll look into it right now.
Interesting, My resolution was 2560x1440 144Hz monitor with Gsync
If I set my resolution to 1920x1080, I have total control over the game it seems
So that was my fix, I loaded the game with 1920x1080 as my resolution. Found the settings in the game, and turned off full screen. Quit. Set my resolution to what it normally is, and that worked out (I wanted it windowed anyways :p). Hope that helps both of you out!
Thanks for the info! I'm working on it right now, should be fixed in a bit.
edit: Just uploaded a new version. the bug should be fixed. It's bit hard for me to actually check since it's screen resolution related.
Thanks again for reporting this! If anyone gets another cursor or resolution related bug (or any bug really), please post it here or send me an e-mail so I can fix it ASAP ^^
