I had two problems with multiple check boxes (Type: Check Box (Multiple)).
First, the items broke on the page odd. So the checkbox for one item may be on the first line, but the line breaks and the item appears on the second line.
So it would look like this...
[ ] First [ ] Second [ ] Third [ ] Forth [ ]
Fifth [ ] Sixth
Also, the vertiacle alignment of the text and the check boxes are off. Rather than being vertically aligned absmiddle with the text, the boxes are all a little higher ... and this makes the check boxes seem odd.
There are two items that I would like fixed ... if they cant be fixed, then these are thoughts for the next version of CB
