To be honest, no. But I saw that the majority of questions there had no responses and thought that this might be a better place, as we seem to be more helpful than that and, apparently, many of us use Trillian.
Edit: I actually managed to find it in their
FAQ, which is, of course, not linked from the FAQ link at the top of the page. Turns out that there's no way to do it cleanly. Of course. I can install a second copy of the software, though. How nice.
The great part is that I tried to move my profile to my ``Documents and Preferences'' directory, since it's shown as an option by default in the preferences dialog from the software's install directory. This has the effect of getting the software to run through the initial prefs config every time I start the program.
