Windows 7, D2 with Expansion. V1.13 I use controller buttons for mouse buttons and game hotkeys (XBCD Driver). I use a normal mouse for pointing only(controller left hand, mouse right hand). The mouse buttons are mapped to the controller using controlMK. This is what I do for all heavy point-and-click games and it worked when I originally installed diablo 2. Some time after, I was playing around with the ControlMK settings and I got some blue screen errors. I reinstalled ControlMK and the BSOD errors havenâ€™t occurred again but now I have a really weird key mapping problem: Whatever button / letter I map "show Items" and "stand still" to, those abilities donâ€™t work now. Diablo 2 recognizes the keypress letter in the key config screen but those specific functions donâ€™t work when the game is active. All Mouse buttons work. All letters, mapped to the controller, work in the chat bar. All other functions work - mapped to any button/letter. The skills still work if I use the regular keyboard. Things Iâ€™ve tried that havenâ€™t made a difference: -Different button / Letter assignments -New Character -Reinstall with registry cleaned (using diablo as keyword) The reason I still think its diablo 2 that causes the error is because all the controller buttons/letters work in the chat panel, just not those functions in game (even though their assigned to the same letters). My theory is that is a corrupt D2 registry entry or corrupt D2 file NOT in the main directory. Are there any D2 registry entries that cant be found with keyword â€œDiabloâ€? Are there any D2 files outside of the main directory that would cause mapping issues? Thanks.
