I still use the VB6 IDE for some projects, but as of today the menu option "File... Make EXE" is greyed out. This isn't specific to one project -- no current or past project will compile to EXE from within the IDE on this machine.
I can compile from the command line using VB6 /make, so I'm not totally SOL, but it's an inconvenience and a mystery.
I can't find this issue mentioned here or on the wider web, so I'm hoping someone here has an idea.
To fix it, reset the menus & toolbars by going to View->Toolbars->Customize->Reset
