If PAGECONTROL as a container, do not open DOCKSITE again, use manueldock and manuelfloat manually DOCK, after using manueldock PAGECONTROL will automatically create a PAGE to accommodate dockclient, but how to manually put it floating out again? Manuelfloat time can't find on which object to use.. (pagecontrol controls dockclientcount display is 0, but clearly there is a FORM was up again into the DOCK, and also automatically create a new page, the problem when using TDOCKTABSHEET controls won't happen)
