I have not tried un-installing full programs while in a live session, but i'm assuming that might persist as well.

This is why I have notes in Vuu-do that says specifically to re-boot after taking the iso for a test drive, as those changes persist and you won't have a perfectly clean install.

Like if you open up Firefox while in a live session, the .mozilla folder will be created and if you then install from that live session it will be there when you boot into the installed system

It's worth a try, boot up liveCD, open Synaptic and uninstall whatever you want, then immediately install system to your computer.

Edit: This is the way my older versions of Refracta-installer work, don't know if this behavior was changed in later versions, fsmithred could tell you if it still works that way.

we will need more information to determine if your equipment is behaving normally.

also for future thread visitors convenience:

Try the desktop-live instead - it will boot into xfce.

ok, everything works now with refracta but it takes a long time, what can i do? eg how can i exclude openoffice or others?

minimal-live: A full-featured, console-based recovery tool with a focus on accessibility for visually-impaired and blind users. Uses the refractainstaller.

you will have better experience with:

desktop-live: Explore the default Xfce desktop before installing. Then install easily and quickly from the live session using the refractainstaller. Firmware is installed but can easily be removed.
