I find that sometimes when I am trying to cycle through open windows of an application with "command" + "backtick" it will only move through a few of them and then go back to the first. The other windows are not minimized or in different spaces. I find it happens most often with my LaTeX editor/previewing/console windows (I use TeXshop). And its not all the time, but I haven't noticed yet if some behavior as I am working that suddenly causes it.
Just wondering if anyone else has had this sort of issue. Its not a huge problem, but it can get annoying sometimes when I need to switch back and forth a lot between the file I am writing in and the file I have to be active on to compile. Thanks!
