[Wine] combo box does not look the same in wine ( vs Windows )

[mctiew]

I have an application, when someone is entering something into the combo box, under windows, it is shown as pulled down, and the entries are dynamically updated into the pull down list.

However when running in wine, the combo is not shown as pulled down. But if I manually click on the pull down button, the list is shown updated correctly, corresponding to what I have entered into the combobox. 

Is there anything I can do about it to fix this problem ? Will dll override work, if yes, how to go about do this ?
