Hey guys, I tried something. I don't even have a EP121 but I made a little EXE under VB.net to disable touch screen. Make sure you read the readme.pdf In a summary: you need to always run the touchscreen.exe as an admin. (IMPORTANT) Once done, Windows will always ask you if you want to run it. If you take a look at the readme.pdf, there's a way to "disable" UAC prompt. Anyway, here's the ZIP and be sure to read the readme! [REMOVED] It's not working on the EP121... Let me know if it works!
