I opened a project in my laptop that was started on the office desktop. My Laptop does not scroll (zoom in or out). The office mouse worked great. Is there something that needs to be changed in Archicad?
I am not saying you can't use a mouse pad with Archicad - can't say I have ever tried it except for moving the mouse.
But it is much easier to just plug a mouse in and use that.
Not always convenient of course if you are trying to use your laptop without a desk.
Does your laptop use some proprietary touch pad driver over the default MS one?
