Help please

I’ve just downloaded the Altititude FS Enhancer for FS9 but as far as I can see it’s made no difference at all. I know it’s in the program and thought that it would at least enhance the scenery and provide more traffic which is what on the box it claims to do, or do I have to actually click something over the area I’m taxxiing or flying before it actually enhances anything?

Neither can I find out anywhere in the FS9 learning centre how to use the ‘slew’ command feature even though it appears in the glossary. When I press ‘Y’ on the keyboard all it gives are the details of the current flight and left or right clicking with the mouse does nothing.

As usual, I’m sure there will be an expert out there willing to give me advice please.

One of these days perhaps I may actually know something someone else doesn’t and be able to start returning some of the advice so freely and willingly given to me over the last few months.
