Bug Description

These a various tasks regarding to keyboard and mouse handling:

1. sometime the Ruskdesk Session will loose the keyboard focus
   so the focus remains on the remote host, or vice versa. At the end either side can not work with the "native" keyboard anymore

2. I am not able to open the context menu with a right click

3. If remote is a windows box. All Menues open only when the mouse button is pressed and NOT released. The normal behavior like a single click opens the menue does not work.
