Hello,

I bought RB a couple of weeks ago and have written my first toy app,
which is a time calculator (it adds hours, minutes & seconds).

I have a G3 and a G4. Since I still use OS 9 on the G3, I downloaded RB
2007 (the last version that supports OS 9) and used that to produce the
Mac version. It works fine on OS X, and also on OS 9 until I quit.
Then, if I choose the Quit menu item, it's fine; but if I type
command-Q, it crashes with RunTimeUnhandledException.

Since I'm not mucking with the menus but just using the defaults, I'm
baffled. I know Mac OS is not supported any more, but does this ring
any bells with anyone here?

I should be grateful for any help.

You may try writing an exception handler. It may even help you figuring out what

The NilObjectException does that. However, others exceptions such as
StackOverflowException or TypeMismatchException aren't.

A RuntimeUnhandledException is not a precise exception (it's the base
class of any exception). It would help to know which exception is being
triggered, and where.
