I have now solved the problem of the first group row appearing in regular (non-bold) typeface at launch and only changing to boldface when the source list is first manually scrolled. The culprit was a call to -[NSTableView sizeLastColumnToFit] in my application's -awakeFromNib, which I had included only because one of Apple's sample projects called it. I never thought it was needed, and once I removed it the first group row now appears in boldface at launch like all the other group rows. My source list using floating group rows now works reliably and without any problems -- at least none that I have found after hours of testing. -- Bill Cheeseman - b...@cheeseman.name _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
