Sorry maybe i'm experiencing the same issue. On my custom style i set up a min width into the style propoerty @pagewidth in the following way:What do you mean "rescales the page upwards"?
If you want to limit the maximum width you will need to set that in the page width controller.
Thanks it worked but when i click on Forum link (forum list) it doesn't work. It seems the width is set to the upper big banner width (leaderboard 728x). Then i refresh page and it resize properly. It seems this happens only on the forum list pages.Yes. You should set a max-width to allow it to shrink.
