Windows 7: Maplestory - Keyboard Problem

Ever since i installed Windows 7 when i try to play maplestory everything works fine EXCEPT the most important part...my keyboard. I have to smash shortcut buttons a million times to get it to work just once. and when i try to move my character left or right he random edges in the direction i pressed or am currently holding. Any ideas? and yes i've tried multiple keyboards.

My last resort was using Vmware Workstation and using it over xp...worked fine but LAGGGEEEDDDDD sooooo much even after direct x 10 and vmware tools were installed. Oh well



If you could fix both of those, or even one of them i would greatly appreciate it

oh and it won't let me run compatibility mode either...an error comes up
