I thought the mouse code was working properly with the Laser, but after playing with it some more, it had its faults. I have two sets of mouse code, both work with the IIGS but only this second code works with the Laser. This also may be more compatible with the mousecard or emulator ROM for the IIe as well. Give this one a try: alt disk image: www.pv3.ca/Apple/Laser128.2mg.zip
