Like AppleShare, for instance? :-)

Seriously, Apple should consider keeping to its own guidelines and
recommendations. I would rather want to know exactly how AppleShare does
go about displaying its dialog box, instead of telling us "you're not
supposed to do that".

If you just want to display something, I think you could use the
Notification manager. Would probably leave a small memory block lying around,
but patching GNE/ST would do that also. (You can't unpatch it because you
never know what went on after your patch.)
If it's more complicated, then it's probably a driver and doesn't need to
patch GNE/ST at all because it gets called at SystemTask time anyway...

So is AppleShare?

Disclaimer: This is just as chaotic as trying to get a dialog showing at
INIT time, although I wouldn't mind being proved wrong.
