Mighty Mouse scroll button [and touchpad double-finger scroll feature as well] doesn't support enlarging or minimising view area in ArchiCAD 9 on Intel-based MacBook Pro 17' under MacOS 10.4.7 operating system.
Same problem here - mighty mouse doesn't scroll. I've got Core 2 Duo MacBook Pro, wireless mighty mouse & OS X 10.4.8.
The problem concerns only ArchiCAD 9, on 10 scrolling works fine but not on 9.
When I switch to using a basic Logitech scrolling USB-mouse, 9 works fine as well.
So what to do? AC9 is up to date and disabling other buttons doesn't work either. Is there anything like usboverdrive for wireless mighty mouse? This really pisses me off
