Keyboard key blocking, mouse button blocking, merging mouse buttons and disable functions like "start menu" turns BasicMouse and BasicBrowser into powerfull kiosk software which is already used by a lot of companies, museums (www.mcq.org).
Run it either with a top console:

Of full screen without buttons except for the next and back button:

BasicMouse prevents the user from accessing URLs not applicable to the function of the kiosk and prevents the user from accessing file system and / or desktop!.
Enter the url's you want to grant access to and BasicBrowser will show a browser screen with only the basic buttons:
Once configures BasicMouse runs on startup of a pc and makes sure the browser (with restricted / specified urls) is the only thing accessible.
Start menu and task manager are prohibited thus making sure nobody can mess with the computer!
With BasicMouse you don't need expensive software to run your program in kiosk mode!
