I already spoke to Tom about this one...
I am writing a DA which opens ResFiles in the System Folder,
loads standalone code from each one--and for now LOCKS the
Handles to the code resources--(of course then closing the
ResFiles). During this I store the Handles in an array of
Handles. The DA then calls each resource with a init
message (same as CDEV, etc.) They all execute and return
properly. (Note that all of this occurs in the "case Open"
in my DA)
Then, however, during the "caseControl" when I call the
(locked) resources with the same parameters, same Handles, etc
Macsbug kicks in with an ILGL err. I know the blocks are not
being moved around, so my handles *should* be valid. Is there
a problem with the fact that my DA's code is possibly being
moved around? What else may be causing this problem? I need
suggestions as I have a time limit on this project! Please,
help out a fellow "struggling programmer" (anologous to the
"starving artist")--if you have any suggestions, small or large,
simply reply to me as soon as possible. I promise I will
somehow return the favor. Thank you very much.

Did you detach the resource handles? If not, then the resources go away when you close the resource file that the resource comes from. > During this I store the Handles in an array of > Handles.

At this point, your handles may be pointing to garbage if you did not explicitly detach the code resources.
