Someone posted this problem back in January with SW 2009. I am running sw2011 and have been having this problem for weeks (months?) I was so busy working I did not have a lot of time to mess around with it. i am now out of work so am trying to resolve. I have done everything from a clean install, ran into problems there so ended up reinstalling (after sys restore). Here is the thread and Kelvin's reply which apparently worked for Nick. http://https://forum.solidworks.com/thread/40761 But it did not work for me. it was set to 4 and I changed it to 0, rebooted, still a problem - here is what my screen looks like when CM is on - please help!
Edit - here is another pic of what happens. If I resize it, I still have no icons and get these funny arrows on top and side. The way I have gotten around no icons is to have a bunch of toolbars(!) - PITA!
