A4000 problem

[spaceman88]

Hi,
  My recently purchased A4000 has an interesting problem. The right mouse button usually won't bring down the top menu on Workbench (when I first got it, it would work sometimes). I tried:
1) A new mouse
2) A different hard drive (OS 3.1 instead of 3.5)
3) Cleaning area around battery (I thought this fixed it, worked for a day or two)
The keyboard equivalent (right Amiga+Alt) still works so the unit is usable. Has anyone else had this problem?

I'll check into that, I tried wiggling the connector with no results and I didn't want to tear it too far apart. :-)
