Im sorry my systemlanguage is german so i dont know whats the same option and settings called on an english OS. Er... i tried to change the windowcolour under the option with lxappearance. For weird reasons changing the windowcolour doenst apply to the windows. Not even after restart. What am i doing wrong?

I also tried to change the themes instead and downloaded a theme i like. Its an .emt data and since im totally new to whole linux and Lubuntu things i have no idear how to set it, or change it to an .obt data.
I already read descriptions how to set new themes but i wasnt able to finde the so calles ~/themes (or something similar) order.
Can someone help me?
Another thing. While i type, EVERY wort i write has red snakelines under it. So opically confusing. How to change that?
greets, sam
