When I change my profile settings from display = thumbnail to list and restart the browser, QV access point will display the content as list.
However, this works for only ca. 5 minutes. Afterwards, the content is listed as thumbnails again. The same happens if I change category to use Favorites, etc.
Is this a browser cookie issue, e.g. the cookie has a lifespan of 5 minutes only?
I found the answer myself. Change the Settings in Internet Options, not to delete the browse history and Cookies when closing the browser... Of Course!
