My text editor (vile.exe) has no menu bar. In Win 10 (mine, anyway), it also has no title bar. Sometimes, when moving this window, I inadvertently cause it to maximize. Once thus, I haven't found a way to change the size back to what it was. In particular, 'size' is grayed-out in the ALT-SPACE pop-up menu.
How might I undo the 'maximization' of this window? Thanks
