I am just start to do my first experiences with bitcoin.
After i reinstalled the Bitcoin client (and delete the bitcoin folder in the user/roaming directory) the settings i did after the first installation - like activate of the proxy - are still present. It looks, that the bitcoin client save somewhere its settings. I expected that the settings i did change are reseted after an new install.
I would like to understand it better.
