black dialog boxes

Since I ugraded to DAP 3, dialog boxes in the browser have a black background. Not all boxes show the black background, though. For instance in the support page ( the search box under “Visit the forum” shows fine, but the one under “retrieve a lost license” is black. No other browser shows this (Safari and Chrome). Has any one here experienced the same? Any ideas about what may cause this? Thanks.

We had this issue just two threads below.
