NulliCedo

I did all you adviced. But still no response of the right or left click of the mouse on the secondary machine. For the clarity; there is a good connection between the primary and the secondary. Even copy and paste of the clipboard works fine. The cursor is also switching. So my only but big problem is the "no" reaction of the clicking of the mouse. It is very pity for I should like to buy your very well program. I am now using trial v1.01. So I can'nt download your mentioned version 1.0

Thank you so much, I will try your advices.

I am using Multicipy Pro 1.01. No problems with switching between my first and secondary machine. But......... the left and right mouse button do not respond on the secondary machine. No reaction at all. It has nothing to do with my mouse for I tried 3 good working mouses (or mice??) Without Multiplicity there are no problems. The buttons works fine on the primary! Many thanks for your answer.
