I do a lot of Find in Files and I've noticed that when I do, files close unexpectedly. For example, I search for Text1 and it finds it in a few files, so I click on its location in File1 and it opens it. Then I do a search for Text2 and a different set of files is shown so I click on File2 to open it. But when I do, File1 closes and I have to redo the search to open it again. And clicking on File1 causes File2 to close. Lather, rinse, repeat. I can't get both of them to be open at the same time. I can see the files disappearing from the Buffers list when they get closed.
