Okay, i still have this issue even after reinstalling SketchUp twice. Once just with reinstall, reboot and install, second time i uninstalled, removed all folder files, rebot and install again.

What happens is I can be in ANY model, just starting or opening a new model and whenever i zoom out (mousescroll) or zoom in(mousescroll) or use any tools from the bar to create or edit entities i lose my axis and the sky. Creating a shape on the axis when it is "missing" shows the line but as if its cutting through the object, see this screenshot please: http://img.photobucket.com/albums/v167/brackishtorrents/Forums/axisdisappears.gif

Im really frustrated as this impacts my ability to use this program and I really like it alot. Any Help?
