Firstly you purchased PTViewer Scripter not PTViewer! PTViewer is free.
You can work out your FOV and TILT parameters using PTViewer applet just mouse over the applet adjust the initial FOV live on screen and hit the "v" button on your keyboard you can then read the exact parameters down on the window status bar.
The settings you then transfer into PTViewer Scripter and then you can save these. The best part about PTViewer Scritper is that it make settings easy for a PTViewer applet display. Making hotspots is easy and this makes creating virtual tours easy without a huge $$$ outlay.
You must remember this program is designed around PTViewer and it's parameter coding.
Things like menu bars, loading screens, button positions and of course the FOV, Pan, Tilt, Starting Position etc.
Mouse over button states is not an option.
Personally I think it is a great program for the money. Maybe you should have played with the trial version before purchase?
