Subject: Re: [IBO] Exploding Application

> Paul,

The application is an MDI application. the child form in question is
created and released from the stack, then after it's released, (using
the release statement), and the main child form becomes active, it
explodes. But so far it's after I modify a record. For the two
variables involved, neither looks like a sane value.

Now there is another MDI child form that is set up to work the same,
and it doesn't give me an error. I am going to look at the
properties, and make sure that they match up. If it's a property
difference, I will let you know which one works, and which one
explodes.

Gee I didn't think Delphi did that, then again anything is possible.

Will do, not sure how much I will do today, my wife spent the last
month dying of a cold, now I have it, and had to cancel two important
appointments today..... I may spend the afternoon watching Star Trek
re-runs on the Space channel. I hear the remote calling me....
