Well, I figured out my problem. It seems that all I needed to do to get
it to work was define a new class that was the subclass of the NSWindow
and in the load method of the main class call:
[ClickDragWindow poseAsClass:[NSWindow class]];
I just thought that someone might care to know.

Basically, I would like to add functionality to (Cocoa) windows in all
applications where command (or some other modifier, perhaps option)
dragging causes the entire window to be dragged around similar to many
X11 window managers. After looking at CocoaGestures with otool for a
bit and noticing that it is installed in ~/Library/InputManagers, I
decided that I would make my first attempt at this using the input
managers.
I can get my bundle to load (verified with a few NSLog()s) and I can
subclass NSWindow and then have my subclass pose as that class. I have
two problems, one minor, one major.
First of all, if I try to add instance variables to the subclass, the
application won't launch. It seems that I cannot do that. That would be
the minor problem.
The major problem is that whenever I quit an application that has
loaded the bundle, it crashes. My + (void) load method is pretty
simple:
+ (void) load
{
[ClickDrag poseAsClass:[NSWindow class]];
}
The only method that I override is sendEvent:. If I don't override the
method it and don't pose as the NSWindow class, it doesn't crash. If I
do either of those (or both), it crashes. So basically it only works if
I only have the load method and it's definition does not include the
poseAsClass: method call.
Here is the crash report:

I've been using TextEdit as my test application although the same has
happened with Console.
I've read the posts in this list's archive so with any luck, this isn't
something that's come up before and I just missed it.
Thank you for any help,
Steve
