I had one ore question. If the plugin is being unloaded (which i
think it is becuase the 2nd time around i can't hit my break points
in my code), how can i tell if i am already loaded if my carbon
bundle goes away? Do i store a pointer to the bundle in the cocoa
plugin? Or will OSX deal with that for me when i call
CFBundleLoadExecutable? I am guessing i would just write my Cocoa
bundle just like any normal with a few "C" calls for calling into the
bundle and an init call (like the docs) that calls NSApplicationLoad.
ok one more question. how can i tell if the bundle is being unloaded?

Is photoshop unloading your plugin?
According to the documentation, "NSBundle correctly loads Objective-
C symbols into the runtime system, but there is no way to unload
Cocoa bundles once loaded due to a runtime limitation."
I actually do everything dynamically. Load the objective-c runtime,
then use objc_msgSend() to call all the things I need. Or call
something that I know will load cocoa for me like
FCCopyCollectionNames() (although I have no idea why this loads
Cocoa on 10,4, it shouldn't since the API it is using doesn't
require Cocoa for anything, but oh well).
Some others just have a cocoa bundle that they load from their
carbon bundle with no ill affects. I do that as well, however my
cocoa bundle only contains a category (too lazy to register a
category on a class dynamically).

and i am getting intermittent crashes. I do call NSApplicationLoad
like i should. The 2nd time i come through the app i don't hit my
break points. Now i saw something about bundles with coco never
unloading so I am thinking this could be the solution.
So my thought was to create a cocoa bundle that is loaded by my
Carbon bundle. I want to use cocoa for the UI. I was wondering if
checking CFBoundleIsLoaded would be a check i should make and
don't reload the plugin the 2nd time around if tis loaded. Has
anyone mixed carbon/cocoa in a plugin? Did you seperate the cocoa
into a seperate bundle or code?
