Apart from gnomes, another possibility might be that you are installing ImageJ inside a directory that gets replaced when something else is updated. Were are you installing it? I keep my copies at the top level of a drive (in Windows, or in Applications in OS-X) where I can easily keep an eye on them and find them to update plugins.
> I mean ImageJ is completely gone (including shortcuts). It doesn't show up in the software list or in program files, and searching my whole computer also returns nothing. I wonder if Gary had it right that installing Java updates somehow affects the program.
