When you use Microsoft Forms 2.0 Controls (FM20) with Office XP or with another Microsoft Visual Basic for Applications (VBA) host application, you may notice a leak in the Graphics Device Interface (GDI) handles if you use the MouseIcon property to change the mouse cursor for a control to a custom cursor. When the property is updated with a new icon, or the control is reloaded as a user form, or a document is closed and then reopened, a pair of handles can be leaked for the process. The handles are not reclaimed until the host application shuts down. If the application is left running for a long time, the system may run low on resources, and you may notice GDI draw problems or low memory errors as they interact with the host application. For Microsoft Office applications, this typically occurs when a document that contains an FM20 control with a custom cursor is opened and closed repeatedly.
When you set the MouseIcon property to a custom cursor, FM20 converts the StdPicture object that is passed by the caller to internal bitmaps (one for the image, another for the icon mask). As these images are applied to form the mouse cursor during a focus or during a mouse event, one or both handles may be leaked.
