Hiding/Showing Avidyne PFD/MFD

Using FS9 on W7

I recently downloaded Avidyne Entegra and installed it, and it appears to be working as expected with one niggling irration (actually, its quite a big one).

The problem occurs on all aircraft that I attempt to use it on, both 'standard' FS9 planes and 'addon' planes from third parties.

The pdf manual which accompanies the software states that clicking in the display area of either the PFD or MFD will toggle that unit on or off, i.e. to show it or hide it on screen. I have found that although clicking on a display will hide the unit, it is then impossible to get the display back again unless I quit FS9 and restart it. Very inconvenient if I click on a display by mistake at an inopportune moment. Perhaps I'm looking in the wrong place - I wouldn't be surprised !

Which brings me to a secondary (possibly related) problem - when this happens I can't simply 'End Flight' and then start it again - if I do the PFD and MFD appear where they should be, but their screens remain blank/black.

regards,
