The scrolling function with the mouse wheel for playing through games is not working? Has that to do with the mouse or is an update of the program required?
The working of the mouse wheel is supported by Fritz. You must, however, activate the function.
That is done under Menu File – Options – Misc.

There you will find the entry “Mouse Wheel executes moves”.
Note: If the option is active, the program does not offer any hints via mouse wheel!
