Not seeing enemy forces/adhering to visibility/detection status I agree is a good next step.
You can only restore the window if you don't have an ExportDLL that is lined up to the bottom of the HC window. So in a default install you have DigMilArt.dll which would hide the minimized window. If you disable those types of ExportDLLs (I renamed mine to DigMilArt.dll.bak) you will then see something like where you can restore the MapWindow form. Please do keep in mind the MapWindow ExportDLL is just a proof of concept at this time. It doesn't do much but when people show interest it encourages me to keep expanding the functionality and someday it will be useful as a result.
