I am not exactly sure what should be done, especially in this case, where the call is ultimately from JS code. Perhaps someone with more Netscape plugin knowledge can fix this or let me know how it should be fixed. 85062 4 zwarich 2008-07-03 06:25:46 -0700 *** Bug 19853 has been marked as a duplicate of this
