I use obconf or lxappearance. Either is sufficient. actually it isn't.
Calling me a liar?
Not smart, Lou. Go read the rules.
And do not do it again.
When I say, "I use obconf or lxappearance. Either is sufficient." you can bet your ass that that is how it works for me. Don't like it? Fine. But don't call me a liar. Just because you have some kind of problem does not mean you get to say such things to me or anyone else. Be polite!
the themes don't draw correctly when switching unless you use both. I can post some screens if you like.
Without more info, there is no way to figure out why your system is different.
edit: it may have something to do with using themes that come with both a gtk3 and a gtk2 version.
re-edit: nope. some themes change with either one, some don't. beats me. might be related to the some fonts work in titlebars and some don't. beats me.
You've been here long enough to know that "it don't work" is not information.
