I have tried using the recording feature to get a mouse click to replay, but it does not work. I used both the Recording and the Mouse entry key (F6) method, and upon playback, the mouse does not click as expected.
A reason could be that you have set the option: "Supress mouse clicking for single clicks and drags" to ON. Then mouse commands are recorded wit a 1 at the last position. Such a 1 at the last position means: do not click....
