I'm a relative newcomer to Eclipse. Yesterday via the "Check for Updates" menu item, I installed a couple of minor updates. When Eclipse restarted, in the Java perspective, I noticed that the "Package Explorer" tab now had a dark yellow background, as did the active tab in the view with all the open Java source files. I thought it was a nice improvement. Today, when I restarted Eclipse, the yellow highlights are gone.
Is there an Eclipse preference somewhere that controls this? How can I get the yellow highlights back?
Edit: I found information that this problem is related to Oomph. The "minor updates" mentioned above included Oomph. Since the original post, I've noticed a number of preferences being lost after restarting Eclipse; these may also be related to Oomph. Should I uninstall it?
