-installed the LATEST DPfix?
-changed dp.exe to run as administrator and enabled compatibility mode for windows 98 and then restarted the computer?
-verified the game file cache in the properties menu by right clicking the game in your steam library?
-disabled the controller input fix with in the .ini file if you are NOT using a control pad?
-tried using a control pad?
Yes to everything, but I did find a solution. I changed my gamepad mapping program to pinnacle instead of Joy2key (Joy2Key had the exact problem as the keyboard) and used a control profile with a matching texture override for the button prompts. It's working well now, or at least as well as deadly premonition could possibly work.
