A font bug exists in AdiIRC. If you change the font for the editbox from Options > Fonts > Font > Editbox, the change is not reflected in the editbox. The default font (verdana) remains, and seemingly cannot be changed. This same issue exists with the monitor panels and the topic box. Attempting to force the change by shutting down the client and manually editing config.ini also does not yield any remedies nor results for this issue.
