I have a problem with a custom master page I have designed for Sharepoint 2010 where the modal popup box is not wide enough and the elements are spilling off the side of the box.
This is the box that appears after having clicked on 'Add new item' or 'Add new announcement'.
Please see the attached screenshot showing this problem.
I thought I could counteract this by setting the site master as the custom master page I have made and using the default v4 system master page for the modal popup however when I do this, the custom master page does not show.
I have to set the custom master page to both the site and the system ones.
It would be cool to hear back from someone about this as this is really getting to me and causing me headaches at work :/
