2.7 Causing Problems with Editor Role?

Hi all,

WP 2.7 is working fine for me, in the Admin role, but my other writer, who has an Editor role, says it is working very, very slowly and her content keeps disappearing. She’s using IE 7.0. She says she’s having trouble saving or publishing content, and that sometimes after a publish half of her stuff will disappear. Does anyone have suggestions?

Thanks!
