## SUMMARY

A change made to MS-TEST WFndWnd() and WFndWndC() may cause them not to work as they did previously. Specifically, treatment of the first parameter of WFndWnd() and WFndWndC() has changed.
Previously, "" and NULL resulted in the caption of the window being ignored. Now, "" means the window must have an empty caption and NULL means to ignore the caption altogether.
