Hi all. Thanks for your replies on this issue, but i think ive isolated the problem. Dosbox seems to function incorrect on my computer, so the fault is software and located in the DosBox program. Some of the functions in DosBox like CTRL+enter(enter/exit full screen) does not work and keymapping dosent work either. I will try to reinstall windows at some point, because ive allready tried to reinstall Dosbos without it helped. I will get back to you whenever the situation changes. Again, thanks very much for your help everyone.
