Write a windows hook which traps WH_MOUSE and WH_KEYBOARD messages and ignores them. You will need to place them in a DLL also with a flag you can set via a function to turn on the ignoring of the messages or not.

Cheers,

Raymond.

If you do a serach on Delphi Super Page (http://sunsite.icm.edu.pl/delphi/) with "hook" as the key you should find some samples.

Also, start reading the Delphi help about DLLs and the helkp for SetWindowsHook in the Win32 help (type SetWindowsHook in an edit window, put the cursor in it and press F1)
Cheers,

Raymond.
