My guess is that this is a problem that since "alloc" returns an id, 
and it finds "initWith:" in several places in the user's code, in 
different classes - which is why there are naming conventions for 
things like this that it should be called "initWithBrowser".  It ends 
up picking a different initWith: method (one that doesn't take an 
NSBrowser), and thus the warning.

If one were to do:

[(BrowserDelegate *)[BrowserDelegate alloc] initWith: browser];

the problem would go away (assuming this is the problem).  The 
correct solution, as mentioned previously, is to use more descriptive 
method names.
