Whatever controls Gnome/Mate users might | use I never install. Also, for changes you make in KControl to take | place you probably have to restart Firefox at least, and maybe the TDE | session.. In my experimenting I've managed to make things worse. In KControl there's a check box "Apply colors to non-TDE applications. I unchecked it and it did not fix the problem, but it did make menus in both TED and non-TED applications very tiny indeed; also the text in, for instance, KMail -- *all* of KMail. I quickly rechecked it, but it did not revert to the way it was before, so I now have tiny text all over the place. No fun. Still trying to figure out how changing colors in non-TDE applications should have changed the font size in pretty much everything. -- dep The shortest distance between you and playing great acoustic guitar: the great new instructional DVDs from Marjorie Thompson, available at www.MarjorieThompson.com

That checkbox is very badly named, the correct name should be "Apply themes to non-TDE application". It additional to colors it tries to apply fonts and ok/cancel order and who knows what else. Also, afaik, it only apply them on checking the box by writing to various config files, so if something also altered this files you have to uncheck and recheck it to reapply. -- Nick Koretsky (nick.koretsky(a)gmail.com)
