Issue with keyboard and throttle after loading P3D4.5

[donjbravo 0]

I updated my P3D to 4.5, to the latest revision.

After I loaded the program, with no issues,  I noticed that my wireless keyboard, or normal keyboard, seems to have changed its own keystrokes or lost a lot of its functionality altogether.   Also the throttle settings from my FDS TQ, using FSUIPC5, that has calibrated OK, have a minimum idle setting of 52%, although the throttle is wanting, from the engine screen, to take it back to the normal idle.  

Whilst the program is running, if I go into windows, and look at any files, if you click on a file in a folder, it highlights everything above it, and will if you click on it, it opens or activate every file above the one you selected. 

When I come out of the program, the keyboard starts acting normally again.

Everything worked well under P3Dv4.4.  Only hardware changes are the upgrade of my graphics card to a Geoforce RTX 2070ti. I have uploaded the latest drivers for this.

I've never had a problem like this before, and cant seem to see any other posts that reflect whats happening, so looking for some suggestions on where to go with this.

Many thanks for all your help
