when I select a point or object in the 3D viewport and try to LMB click drag it somewhere with snapping disabled, the point moves in all directions but not where I would like it to go. It seems to prefer the Z axis and move away from the viewport camera as far as possible.

At first I thought it was because I'm using a Wacom, but using a mouse gave me the same results.

Is this a known issue, or do I need to change some preference ?

Thanks,
