Subj : Re: Narrowed the problem down to...and solved To : netscape.public.mozilla.jseng From : "Sterling Bates" Date : Fri Nov 07 2003 10:44 pm Turns out the breakpoint is raised anytime my code is anything but perfect -- and that can be arbitrary. In one instance I was using a JS_NewString(...) to create a JSString, but the problem went away when I changed that to JS_NewStringCopyZ. In another instance (discussed in this thread) the JS_DefineObject problem was caused by including the wrong Delphi file. I had the right structure definition in both files, but I guess Delphi differentiates between identical types from two different files. Anyway, thought I'd post the solutions in case anyone else out there finds the breakpoint issue. Sterling .
