I know there have been some previous posts about the File Structure windows and not setting it to auto-hide - no problem. I have mine docked next to the Solution Explorer and the Properties tabs. Unfortunately, it doesn't show up by default. See FileStructureMissing.png. When I select ReSharper | Windows | File Structure, it magically shows up. See FileStructureFound.png. However, if I select the Solution Explorer tab, the File Structure tab disappears and I'm back to the FileStructureMissing.png screenshot.
Has anyone else seen this?
