I purchased Nibiru: Age of Secrets the other day and installed in on my computer (Vista OS). The first few scenes work fine and then my cursor disappears. I turned on the feature that allows me to see where the cursor is by pressing Control, and the cursor is still there just not visible. Nor does it work if I attempt to click on something. I contacted the company’s technical support but they haven’t gotten back to me… I’d appreciate any ideas. Thanks!
