PowerPoint 4.0 Does Not Recognize Double-Click Macro Article ID: Q113734 Revision Date: 09-SEP-1996

The information in this article applies to:


 * Microsoft PowerPoint for Windows, versions 4.0, 4.0a, 4.0c

SYMPTOMS If you use a mouse that has been programmed so that a single-click of one its mouse buttons should be interpreted as a double-click mouse event by Windows, this will not be interpreted correctly by PowerPoint. One example of a mouse that provides this capability is the Logitech three- button mouse. If you program the second or third button to Double-Click (when clicked just once), PowerPoint 4.0 will will interpret this as a single click. Word 6.0, Excel 5.0, and PowerPoint 3.0 will recognize the programmed button. For example, if you insert a graph into a presentation, you can edit it by double-clicking it with the left mouse button. When you use the programmed mouse button instead, the graph will be selected, but the graph editor is not invoked.

MORE INFORMATION Many Windows-based applications use a Windows programming call named WM_LBUTTONDBLCLK to detect a double-click. Because PowerPoint 4.0 also supports triple-clicking, it recognizes the difference between single, double, and triple clicks by detecting discreet mouse clicks (using a call named WM_LBUTTONDOWN) and timing the interval between them. PowerPoint does not use WM_LBUTTONDBLCLK to detect double-clicks. If the mouse program macro relies on WM_LBUTTONDBLCLK call, this will be ignored by PowerPoint. There is no workaround for this at this time. If you want to double-click something in PowerPoint 4.0, you have to double-click with the left mouse button.
