can't change picture format

Hi guys,

i love the features of the new 3.0 version. I am only facing one problem: when I add an "image field" from cck into a view, then i can't change the format of the output of the picture. It always shows a link to the picture instead of displaying it directly in a view. When i change the option and click refresh - nothing happens and the option does not change.

Does anyone have the same problem or has an answer for me? I am using views 3.0 alpha3, cck 6.x-2.6 and imagefield 3.2. Should I try to install a developer version of CCK (like 6.x-2.x-dev ?)
I tried it in different browsers and created new views but the link to the pictures does not change.

Thanks alot,
