Are you running the app in debug mode? I've made the mistake of trying to debug in "release" mode a few times, and it often shows some insane values for variables.

In general the naming convention used in Objective-C is that class names start with capitals and variable names start with lower-case characters (both use bumpy case which I think you know). For instance NSWindow (class) and aWindow (variable). However in your code you have LASize, which looks a whole lot like NSSize (which happens to be a struct). However you're assigning sender to it which is of type id. This introduces some confusion, since you assumedly assign an object variable to something that looks very much like a struct type. This may not be a bug (we don't know what type sender or LASize are so it's hard to say), but it leaves the code nearly unreadable for the casual observer. If you want someone to help you out, try to post more clear code. In a more general sense, it's good to write code that follows the general naming conventions anyway since if you ever have to share your code or go just back and read it in a year you'll have less work understanding it.

Thanks for the advice--I'll try to follow it more carefully. I should have included the declarations, in my .h file, to make the example clearer to all.

In the meantime, I have gone on to explore the question, and I may have discovered a problem with the debugger. Perhaps the list can advise me:

If I insert the following code into my program, with a breakpoint immediately following, the debugger shows ridiculous values for the elements of aRect.

        NSRect aRect;
        aRect.origin.x = 310.0;
        aRect.origin.y = 15.0;
        aRect.size.width = 100.0;
        aRect.size.height= 100.0;

When I sent my original posting, I was trying to discover how the structure had been corrupted. It appears to me now that it hadn't been corrupted at all, but was being misreported by GDB. Should I submit a bug report?
