Ha ha! I kid you not, based on my experience: If you have ANY Acer software on the computer, it will slow the trackpad! I don't know why, but it just seems like it's all or nothing. Not only does the Acer software slow the trackpad, but I always get extreme bloating in my system Temp folder! After a few days there is like 26Gigs of Acr temp files! Once I delete and uninstall the Acer stuff... no problem.
