Hi David,
Doesn't this only apply to windows that have been set as "always on top"? I know that the main VFP window (for example) doesn't show as WS_EX_TOPMOST in Spy++. When you take an old style help file (as you mentioned) and set it as always on top, it has this property. When you set it back to the default, it doesn't. I'm not sure that this is what Bill was looking for.
