1. The 'knoppix-version' file is missing from the KNOPPIX folder. 7.4.0 was also like this. I went to see what version the KNOPPIX folder was on a drive and it wasn't there. Had to goto a mirror site and look at the file timestamps to get an idea.
2. The toolbar clock color in KDE is white. With cheatcode no3d the toolbar is solid and near white. This makes the clock white on white with shadow, barely visible

This one is strange, in KDE, if one of the first things you do after booting is click on the 'KDE Accessible' icon in the tray, it will take over 2 minutes for the window to appear, In that timespan you can move the mouse but nothing you click on gives any response, At first I thought it locked up, sure looked like it did.
It's tempting, because it gives no tooltip, and it and the KDE-menu are the only color things on the toolbar when you first boot.
If you do other things after booting and later click the icon, the window pops right up.
4. on the EN version, in iceweasel, under Bookmarks, 2 folders are in German, and the KNOPPIX bookmark toolbar goes to
