The 3D appearance of the multicolumncombobox is different to the TIWComboBox, TIWAdvEdit, and TIWAdvLUEdit. The top and left borders are heavy black compared to the other three which looks odd when combined on the same form. Is it possible to change the appearance of the MultiColumnComboBox to match the others?
PS. The control reverts to the same appearance as the other controls when it receives focus.
I am running Firefox.
Can you please try setting the TIWMultiColumnComboBox.Color property to clNone?
Thanks. That fixes the problem.
