Tooltip

Reports :: Tooltip / Popup Text Box / Floating Text Box?

I have a report that lists incidents for a specific day (reference number, a brief description and a few other fields). There is also an additional notes field, which I would like to be viewable from within the report.

For example, as a tooltip when the mouse hovers over the brief description text box. Or displayed in a textbox on the right (I don't want one textbox per line though, but instead a single re-usable textbox). Or a more information button/link that shows a "popup" containing the additional notes. I don't want to exit out of the current report, but stay within it.

I have tried to achieve this with a tooltip, but in fact even when I manually typed in a tooltip on the control's properties it wasn't displayed when I hovered over the text box.A pop-up or floating textbox would be preferable.
