Once debugger is hooked up, the message should be (hopefully) seen (unless the app eliminates stderr completely). Point is that this isn't supposed to happen at all, and right now eveyone's goal should be to figure out whether it actually happens or not. If it does, then this code won't go live anyway. If it doesn't, this debug message won't be relevant. -- O< ascii ribbon - stop html email! - www.asciiribbon.org
