TV 14 controls not working as claimed

I have installed TV 14 onto my Nokia 5 ANdroid phone and onto my WIn 7 32 and 64 bit PCs

I can open a session, but stuff does not work as claimed.:

- Using a 2 finger drag does not scroll ( in fact at one time I swear it chaned the PC's volume)

       the only way I can "drag" is to use the mouse cursor, dragging in "reverse" so that the curso moves the PC screen across my phone as it reaches the edge of my phone screen

- The volume cannot be dragged by the mouse cursor; I have to place the cursor above or below the volume slider and then tap my phone screen to raise or drop the volume according to the relativce positions of the volume slider and the mouse cursor. This results in a large drop or rise in volume that is set to go from 0 to 100% in about 5 jumps.

At this stage, altering the volume of the PC while actually watching TV, with the TV connected to the PC's audio input, was all I wanted.

Is there any possible solution to this?

Thanks for any help.
