Thanks for all the help, Matty and deAd. I haven't had any experience using functions like Interop.Call or the Windows API, so I'm having trouble getting the hotkey code to work.
Furthermore, I have exams starting this week, so I don't have any time to work on scripting...
If anyone does have time, I would have no problem with if they wanted to take over working on this script.
As for the preferences window, that is (again) something that I have no clue how to do.
Sorry for not being able to do much with this script (I've only been scripting for about 3 months). If you can do any of the suggestions, by all means, feel free to do it! I better get studying now...
