Buttons work (I can right/left click), but not the movement detection.
Is the keyboard lock locked?
Please help if you can: I need to transfer tons of data to PC and moving the cursor with the keyboard (A-arrows) is not the most comfortable way do work...
Connect the harddrive to your PC and use WinUAE to transfer files. It's much faster than any networking or external harddrive solution for the Amiga.
If you don't want to use the mouse, then use a DOS shell (CLI). DOS commands can be entered using the keyboard only and are much more flexible than Workbench drag&drop.
