You can set Tyre in a 'sleep mode' by clicking the 'Hold' button. In this mode, the program will no longer retrieve locations from the clipboard. This can be handy, if you want to copy some locations to the clipboard to use them in another program. TomTom Files are limited up to 48 waypoints. If you are creating a route file that is larger than that size, you will receive a message and you can remove one ore more waypoints. If you need to create a route that contains more than 48 waypoints, cut the route into two or more routes. On driving, when you reached the end of the first part of the route, load the second file and continue the route. Google Earth does not give a placemark a very handy name. They are all called a 'New Placemark'. It is useful to change that silly name into a more recognizable name (e.g. the name of the street where you put your placemark) before copying the placemark to Tyre.
