When I right click a tab and click bookmark this tab a window apears with the option to select where you want the bookmark to go. If I click the bookmarks menu next to folder a dropdown box appears to offer me the different folders to save to. The dropdown box used to be white but is now black and has no text. If I put the mouse over one of the entries the text apears only in that entry. If I click the entry called choose the new box is white and everything is fine. It is the previous box that is black that is the problem. Somewhere the text box attribute of this box is set to black. Where can I change that?
