Problems with WPTools using TAdvPanel

We are using TAdvPanel and TAdvOfficePager in our design, and discovered a bug when using WPTools' rich text component together with the panel or pager. The rich text component works as it should with TForm/TPanel/TPager as parent, but if a TAdvPanel or TAdvOfficePager is parent (or in the structure beneath the parent) the marker (text marker) disappears when trying to set focus to the editor. When we click in the rich text editor the marker blinks for a second before disappering again. Looks like maybe a problem with focus or something? This problem only occour when using TMS design components like TAdvPanel, TAdvOfficePager and so on. We have updated both TMS and WPTools to the latest version before posting this topic.
