Correct. The existing Notepad is top level Window and menu bar around the existing [edit control](https://msdn.microsoft.com/en-us/library/windows/desktop/aa368342\(v=vs.85\).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/aa3...). It has always had the same limitations - eg in way earlier versions of Windows it was limited to 64kb of text. Addressing the "bug" is not simple - the edit controls behaviour could be changed in which case it could cause existing programs to behave differently, or extra code would have to be written for notepad to do its own text editing. Microsoft takes backwards compatibility very seriously. Anyone curious about the Microsoft side of this should find Raymond Chen's Old New Thing blog interesting (about 5 posts a week). For example here is content tagged history: https://blogs.msdn.microsoft.com/oldnewthing/tag/history https://blogs.msdn.microsoft.com/oldnewthing/tag/history and here is how there are actually two copies of Notepad on each system: https://blogs.msdn.microsoft.com/oldnewthing/20090312-00/?p=18843/ https://blogs.msdn.microsoft.com/oldnewthing/20090312-00/?p=...
