Sorry Egonz here's my reply to your first comments. When my PC starts up and I log in I want to have my 'boot' theme load. Unfortunately LS seems to load whatever the last chosen theme was (which is logical for most users). Once my 'boot' theme loads I then select a theme from some buttons placed on the screen. Most themes are pass-worded which stops my 3 year old hacker son breaking my PC (but doesn't stop him smudging the screen with chocolate!).
So I have figured out that I can always boot into my theme usingin the Winlogon/Shell part of the registry but when I do this I have problems with the mzscript.dll module.
Also, did you know that OTS is a theme standard for LiteStep, and not a distro :P
