My nephew is sometimes coming over and I would accept any bet that he is heading straight towards the computer pressing buttons and moving the mouse around if not supervised. This can cause some irritation and probably damage and I finally found a way to stop him. This is actually helpful in numerous ways, have you ever tried watching a movie with a kid on the computer? If the kid is young he or she will surely hammer away on the keys and move the mouse around which is a huge distraction obviously and can even lead to situations where things break or get deleted.
Then I discovered Toddler Trap by Skrommel a member of Donation Coder. Toddler Trap is like a filter that takes all the pressed keys and mouse actions and suppresses them. When activated, pressing a key or a mouse button will have no effect on the computer, there is no way to close windows or open right-click menus. Some special keys are still working but the Windows key for instance is blocked as well.
So, whenever he comes the first thing I do is start up Toddler Trap and let him have his fun. I don't have to worry anymore and he is happy. The Toddler Trap window centers on the screen but it is possible to move it away from there. The window will always be in the foreground to catch all the input and this proves to be a problem when watching movies.
You can move the Toddler Trap window with the mouse normally but it will not be released until you press Return.
A click on the small x in the interface closes the program again, which means there is still a slight chance that children will be able to close the program to wreak havoc on the PC again. Check out the related articles section below for additional tools to protect a PC from children.
