SYMPTOMS
If you open and close a large number of workbooks, a slowdown in computer performance and "out of virtual memory" messages can occur. Eventually, if left to continue, the program may stop responding (hang) or generate various errors. The amount of time before errors occur depends on the amount of memory available and the amount of memory the controls on each workbook use.



CAUSE
When opening a workbook that contains an ActiveX/OCX control, the Excel process acquires a minimum of 20 private bytes. It does not release this memory when it closes a workbook, but only releases it when the Excel process ends. The amount of the private byte leak can be greater, depending on which ActiveX/OCX control(s) you use in a workbook. You can observe this behavior within Windows NT Performance Monitor or other similar tool.
