I play fast and loose with some menu options. Sometimes selecting a checked option will simply uncheck it. Sometimes it will bring up whatever was enabled and expect you to uncheck it again if that was your intent (using the menu option as a temporary "show me"), and sometimes unchecking an enabled option will come up and ask if you want to simply disable or completely remove the option.
No, that is not the expected behavior. Mine doesn't do that, but then again, mine is constantly updating and never disappears on the time.
Does it only grab focus when a new frequency is detected and the window isn't already visible, or does it even do it with an existing window that updates with a new frequency?
What version of Windows are you running, it may make a difference as I'm on Win 7 Pro 64 bit.
