I use Eclipse 3.3 in my daily work, and have also used Eclipse 3.2 extensively as well. In both versions, sometimes the Search options (Java Search, File Search, etc) in the menu get disabled, seemingly at random times. However, with Ctrl+H, I am able to access the search functionality. Does anyone know why this happens? Has it been fixed in Eclipse 3.4?
I don't have an exact answer. I will recommend that you try to correlate the disablement with which perspective is active. Likewise, which view is active. I have been using 3.4 and not experienced this issue.
