The SharpEnviro site's down, so I'm posting here an update to some notes I've been compiling regarding a crashing toolbar that features an ApplicationBar module. I'm now certain of the cause of the crash and can duplicate it at will:
* The crash definitely happens in FireFox when I change pages to one that has a *huge* number of characters in the page ttitle. FF uses the page title as the caption, so what's happening is that the ApplicationBar module is crashing when it retrieves an application caption that has a large number of characters in it. Buffer overflow anyone?
The crash happens on my computer often because my bug tracker (Roundup) uses the text of the currently-viewed bug report as the page title, so stack traces and whatnot included as part of a bug report make FireFox's application title very wide. I'm sure you can duplicate the problem in Delphi by creating a little program that sets Application.Title = to a large string.
