When I click on a part in an assembly, the design tree on the left does not expand. Only the sub-assembly gets highlighted where the part is located. To find the needed part, I have to manually expand the tree and search for the part. A month ago, everything was working fine, and my co-worker's solidworks is working fine too. The "scroll selected item into view" is checked in Feature Manager. I have restarted the computer, still no luck. My last resort would be to reinstall the program, but I'm hoping there is a simple solution.
Any advice would be helpful. Thanks.
