I'm not overly experienced with Sharepoint, but usually my Google-fu is pretty good...until now. Office 2007, SP 2007, Win7/Vista environment, I am a subsite administrator. When viewing a multiple-line rich text field in Datasheet view, any text entered in the column is automatically formatted with black highlighting on black text.
Most of the Google results deal with changing the sheet background color, which apparnetly can be modified via the CSS; unfortunately, this is not my issue. From poking around with IE Dev Tools, I can't see any CSS being applied in the Datasheet view at all.
This technet thread here suggested disabling Norton, which doesn't apply in my case, or changing the default font of the Datasheet view from MS Sans Serif (which is apparently not well supported in Vista/7, being replaced by Microsoft Sans Serif). Unfortunately, I don't know how to do this, so I can't verify if this fixes the problem.
My workaround is to change all rich text boxes to plain text boxes, but that involves a significant loss of functionality. Any thoughts?
