You first make sure that you have the latest and greatest version of mICQ - the bug might have already been fixed. Also check the mailing list archive if it's mentioned there, and, of course, this FAQ. You might also check the version in CVS, or this page in English. If you still think you've found a new bug, please report it to me, and please report as much detail about your setup as possible. If you can provide a fix, that would be appreciated very much, but, because of the speed mICQ evolves, if possible create a diff against the current CVS.
