I have a problem with my MX-900. Recently it's started to scroll many channels when I select either channel up or down. I've replaced the batteries and have the same behavior. It exhibits this with both IR/RF modes.

Second problem is I thought I'd upload the remote programming to the MX-900 editor and take a look at what it at least thought it was trying to do. Unfortunately I get a can't connect SC-1 error. I'm running Vista and not sure if that is the problem. I've seen other recommendations about disabling bluetooth wireless keyboard and mouse, and was about to try that when I saw a reply it didn't work for someone. I am using USB2 directly on a Dell PC, no USB hub issue. Tried changing ports and no luck there either. If someone can suggest solution to the first problem, I won't bother with the second.

Thanks in advance for any pointers!

Try deleting the IR codes from the buttons and replacing them from the IR database. If not success full, try deleting the IR codes for those buttons and learning them.
