LexisNexis is reporting that the newest version of Safari for the Mac will crash if you conduct a search in LexisNexis Academic.
LexisNexis is trying to fix the problem, but it sounds as if the problem might be more with Safari. Suffice it to say that if you search Google for “safari crashes” you will have to go through several pages of results before you find anything about a plane crashing in the jungle.
In the meantime, Mac users who want to search LexisNexis Academic are advised to use Firefox.
