I use POL 3.5 on ubuntu 9.04 but when i select a specific wine version for a specific application with the version manager simply nothing appen...if i run winecfg for the application the version is every time the version selected for default in the "environment" tab.

Hello Ubuntoz,

Selecting a specific wine version for a specific application work, it's just that the "About" tab in winecfg doesn't show the right version number.
See Tinou's third answer in the second post of this topic.

Bye

P.S: Please make an effort on politeness, it's not so hard to say some kind of "Hello" and "Goodbye/Thanks"
