What is your right key supposed to do?
How did you disable touchflow?
Have you checked the registry setting? It may not be correct if you have touchflo turned off.
Does the program referenced by the registry setting exist and/or work with touchflo turned off?
Here's a link to the registry key setting for Manila. I'm not sure if it works when you have touchflo turned off, but you haven't given out a lot of information.
