Problems with custom preview in Font Book
I just recently upgraded to Mountain lion and noticed that when I am browsing my fonts in Fontbook using custom preview that some fonts will switch to sample preview. But when it does that the preview pane gives me a sample view of all the weights of that font. For example: As I scroll down through the list of fonts using custom preview and I get to the Arial font the preview pane will switch from whatever I haved typed into it to a sample preview of Arial, Arial Italic, Arial Bold, and Arial Bold Italic. I can use custom preview for those fonts but I have to select the weight of that font in order to do it. Is there a way to turn that off or fix it so I can quickly browse through my fonts using custom preview?
*I did not do a clean install of mountain lion and I also have adobe font folio loaded into my fonts.
