Way back when, I wrote:

 The question is:  If the DA is open, accessing this helper file which
contains the cdev resource, will the Control Panel be able to still load

wb1j+@andrew.cmu.edu (William M. Bumgarner) responded:

no can do.  I just opened Pyro! with Resedit, and then opened the Control
Panel.  After clicking on the Pyro! ICON, CPanel returned 'CPanel cannot load
resource file'.  closing in Resedit reenabled Pyro!.

And erics@eleazar.dartmouth.edu (Eric Schlegel) then responded:

And now, I respond:

Well, for one, I have been informed that when you have a resource open it is
for read and write, not one or the other.  Don't quote me on this.

At any rate, my original question is moot.  We've decided to scrap the cdev
seeing as it is rather odd for a cdev to control another programs options
(in this case, controlling how a remote server alerts you to new mail.  the
mail DA itself will now handle these preferences)

Thanks for the help anyway...
