"Show Blocks" behaviour - Mac Safari 3 vs IE/FF

Hi,

A client of mine periodically uses an Apple Mac to add/edit content in FCKEditor (v2.6.4). We have noticed behaviour which differs between Mac Safari and other (Mac/non-Mac) browsers such as IE and Firefox. In a new instance of the editor, when she clicks "Show Blocks" in Mac Safari, nothing appears. In other browsers I've tried, an initial P block appears.

While this isn't a major issue, has anyone else seen this behaviour? There are other quirks relating to Safari 3 usage too, but it would be good to understand this issue first before going into more depth.

Thanks,
