Many times, especially when I've been presented dialog boxes regarding site security changes, a dialog box will appear with a title and OK and cancel buttons but no text. In addition, I've had problems with dialog boxes (usually without text) with sizes so big that I could not actually get to the OK and cancel buttons -- they would appear below my screen at 1024 by 768 resolution. Surely no dialog box would intentionally be THAT big, would it?
Reporter what build Id are you using?
My apologies for leaving that out. Currently experiencing the problem on Mac build 2001040908, but also experienced the problem on 2001040608 and earlier builds. The example that occurs most often for me is when logging into Yahoo! mail securely (https://mail.yahoo.com/) -- while the initial dialog box does show text, two further "Security Warning" dialog boxes after submitting the username and password show as blank.
