A recent request on a listserv I subscribe to wanted to know if there was a free mouse trapping option where the user could select the region for the pointer to be fixed. A couple of suggestions were made, but one was quite old and the other wasn't free. So as this did not seem to be too difficult a task which could fill an hour or so, I decided to see if I could make a better mousetrap than the one i originally posted here. And what better name for an app than, "A Better Mousetrap", so here it is
A very simple application, choose the area you wish to trap the mouse in using the movable and resizable glass window, then press the hotkey combination to lock the pointer in the field. Once an area has been set, the application will retain that setting until either a new area is set, or the application is closed. This will allow the lock to be turned off whilst navigating elsewhere and then with a press of the hotkey combination, the lock can be restored.
