Mate Controlled motion simulation works only if being shaken

Hi,

Please advise,

I am trying to make a simple XY motion simulation and I tried few ways and none is working correctly.

The Mate Controller may work correctly or may not when closed and open again or deleted and created in exactly the same sequence again.

In most attempts, the Mate Controlled assembly moves only if assembly literally being "shaken" by 3D mouse while moving is in progress otherwise it stands still.

This Mate Controller behavior is the same and weird for number of other simple applications I have tried.

Please advise whether it any chance to make it work as designed.
