Hi,
With all respect, the best place to ask would be the Sim Skunk Works forum. You may be waiting on access to it? I have always found them to be very helpful with any queries.
While you're there check out the Users Benefits section and the "Bombing Ranges" thread in the F-84F section. You will also find additional maps which were created for the Tornado but should work with the Harrier too, as I believe the RPMD is the same. The link for these is on the Home page under the "How to Get Tornado" header.

I will try to help anyway:
1/ Try using the mouse wheel to rotate dials. Otherwise try left or right mouse buttons.
2/ It sound like Websimconnect is not starting (Red Panda). This needs to be active for most SSW aircraft, and there should be an entry in your P3D EXE.XML file which instructs it to start automatically with the sim.
<Launch.Addon>
<Name>RedPanda_Launcher</Name>
<Disabled>False</Disabled>
<ManualLoad>False</ManualLoad>
<Path>.\SimSkunkWorks\WebSimConnect\RunProcess-x64.exe</Path>
<CommandLine>--appname=RedPanda.exe --cmdline=-start -port=2048 -folder=www -errmsg=Red Panda did not start, launch it manually</CommandLine>
<NewConsole>true</NewConsole>
</Launch.Addon>
3/ That happened to me for a while too - only in FSX. I deleted the SSW "Trusted" entries and then after re-allowing them I didn't have the problem again. There is another fix for that on the forum, but it is a bit complicated (and risky) to post about here, as I have not tried it, so I can't confirm the steps.
The post is called "Those pesky DLL certificates".
Cheers,
