I just noticed that if I have a column in a DW with a DDDW edit type, and a tooltip defined, when that column has the focus (so the entry in it appears selected) hovering the mouse over it will not pop up the tooltip. Hovering the mouse over its drop-down arrow at the right will still pop up the tooltip. And if I hit Tab and move the focus to another column, that first DDDW column shows the tooltip normally, when hovering over its contents.
Is there any way to avoid this behaviour? Is it a bug that should be fixed?
