remove textbox background

[uoghk]

Don't know why the 3 textbox show background color.
I check all the format properties of these 3 textbox are the same as the others.
I also delete these textboxes, then re-create them by coping from the others.
But they still have background color.
I also find the in Report Designer, when in Report View, they are OK, no background.
But in Print Preview, they have background again.
