Rhino Repeating Command Problem

Hi, I am recently facing a problem - when I click the right button of my mouse to drag the scene, repeatedly I get the last command repetition. It has been very much annoying. I did not face this problem earlier.

Could you please tell me why this has happened all of a sudden and how to solve this?

Hi -

This is most likely a hardware issue. You might want to try a new mouse.
