OpenPHT new installation issues...

I just installed OpenPHT 1.5 on my Windows 10 desktop PC and ran in a few issues.

1. How to enable the use of MOUSE inside the OpenPHT app?
2. How to enable earphones instead of speakers? I only use earphones on my PC?
3. I have two movies titles on PMS but only one title is shown on Open PHT app. Any ideas?

Thanks in advance...
