Summary

Symptoms

A Combo Box control has been added to a dialog in a Basic MSI setup, the control does not drop-down at run time even though the arrow associated with the control has been clicked. This prevents items from being selected from within the Combo Box control.

Cause

This issue occurs when the Combo Box has bot been specified to be high enough. You can specify how high the control should be in the "Height" field for the control within the dialog editor.

Resolution

Set the height field of the Combo Box to 100. Now, it can be selected from the Combo Box at run time.
