btw, I re-re-reinstalled E-17 Light and one, I have no oxygen icons now, and Chrome minimizes and maximizes to iTask-NG the way it does in E-17 full. I had downloaded at least two different copies of the .iso. all said the checksum matched. at this point I'm thinking something on my Mac that runs in the background, or VirtualBox itself is just corrupting some guests randomly. I'm not as dense as I must seem at times. lol
I don't have a clue how I got any copies of the Oxygen icons however. I know I didn't install them. I'm not a big fan. the only thing I can figure out it some other icon set I installed to try was named incorrectly in its theme index file. But, they do looks like Oxygen. beats me.
