On OS X using a trackpad pinch gesture to zoom in / out breaks panning and zooming. When a drawing is opened or created, pan and zoom functions work as expected. As soon as you use a pinch gesture to zoom in/out all zooming and panning operations (toolbar buttons and scroll bars) begin producing erratic behavior. The drawing has to be closed and re-opened to restore proper operation. Other open drawing windows are not affected and work properly unless you pinch gesture zoom in their window.

This task depends upon

I have this same problem on the latest QCAD on a Macbook Pro. Using the trackpad to pinch or zoom then breaks the panning function. I am happy to test new builds on my machine to see if we can fix this.

Same on Macbook Air. Suddenly becomes unworkable when try to zoom. I don't know it its just the pinch gesture on the trackpad, but I have needed a restart at times to get it working again.
