I was trying to map one day and I can't seem to be able to change the CS, AR, and OD. I know where to go, but this is the screen I get whenever I try to change it. I seem to only be able to change HP. Anyone have any idea why my screen is like this?
Looks like some sort of bug. Might have something to do with the font or .NET framework but I'm really not sure about that. You can temporarily dodge that problem by going File -> Open .osu in notepad and changing the numbers by hand in the appropriate lines.
I will stick with editing through the .osu file. I did try what Veilstar suggested, but it crashes my game. So, when the time comes, is there an alternative way to upload a beatmap without sending it through the game?
