Hello board. I do inspections for the insurance industry, and we use Apex IV Insurance version 2.91.1073.1. I am having an issue with the curser jumping slightly while I am in the middle of the drawing. I'm using a lenovo laptop with a touch pad and the red button in the center of the keyboard. I have the pad disabled as that was giving me way too many strays. I am using a usb wireless lazer mouse, but even when I'm sure I'm not moving it, or the pad, or the surface everything is on, I still get jumps and hiccups. Drawing the same wall four times is getting old. Any suggestions?
