 Last reviewed: January 16, 1995

  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

SYMPTOMS

When a combo box with the CBS_DROPDOWN or CBS_DROPDOWNLIST style is used inside a system modal dialog box, it causes the following problem in Windows versions 3.0 and 3.1:

  1. An item cannot be selected from the drop-down list box by clicking it with the mouse. The original selection remains in the edit control or static-text control.

Using a combo box with the CBS_DROPDOWN or CBS_DROPDOWNLIST style within a system modal dialog box in Windows version 3.0 causes the following problems:

  1. The drop-down list box cannot be closed by clicking on a part of the list box that lies outside the dialog box.

  2. The parts of the drop-down list box that lie outside the dialog box are not erased when the drop-down list box is closed.

CAUSE

The mouse messages meant for the drop-down list box never reach the list box.

STATUS

Microsoft has confirmed this to be a bug in Windows versions 3.0 and 3.1. We will post new information here in the Knowledge Base when it becomes available.
