"What's This" fails in KControl?

Latest GIT. Would somebody confirm whether the "What's This" tooltips work in KControl? Simply "right-click" on a check box text string. A popup should appear with the text string "What's This?" and when selected, a tooltip help string appears. The "What's This" tooltips work correctly when I start a KControl module from the minicli or from the TDE Settings menu. They don't work when I try to use them in the full KControl. Thanks. Darrell
