How do I swap to different spells on PC, Google says to use the F keys but they don't work.

So I've started this game a few times but I eventually stall because I get tired of running around lost. Does anyone know of a good map?

Hey, after many years I wanted to play this nice little game again and now facing the same problem as allready many player reported: While using Keyboard and Mouse controls, mouse buttons very often get stuck, so using sweeping correctly is nearly impossible and minions often get sent or recalled when you don't really want it. This way you can still do some basic fighting, but as soon as you have to do some more complex tasks where proper leading of your minions is needed, it's just frustrating as hell. ...

Started a new file, but every time I try to save or the game tries to autosave I get an error that it Fails To Save (error window is in the normal menu text and graphics for in-game menus). Not sure what is going wrong but has anyone else run into this problem?...
