4-column dashboard layout warped

[solarissmoke]

When you pick the 4-column layout on the dashboard, there is an issue with minimum widths that causes all the columns to overlap, and meta box content to overflow from containers. See screenshot.

I thought this was the reason behind being able to set the number of columns there, so the users can choose the layout that best fits their screen size. The only improvement here would probably be to set min-width so the browser window gets a horizontal scroll bar.

Turns out that this is browser-specific. I can only reproduce it on FF on Linux. On windows, there is no overlap, and the boxes are properly spaced. On Linux however all the meta boxes overlap.

This works fine on Firefox/Linux now, consistent with Chrome. Whenever the width is reduced to a level which should cause overlapping, its wrapped up into 2 column layout preventing any overlapping.
