Strange Behavior On Forms (Access 2007)

All -

I've run into 2 things when working on Forms that are driving me crazy...

1.  In Form View, some Combo Boxes will go transparent after tabbing or 
moving out of the Combo Box.

2.  In Form View, some labels will gradually get more bold as you Page 
Up/Down through records.

Has anyone found a fix for either of these yet?

Thanks.
