PRB: Context Help Not Compatible with Min or Max Button

SYMPTOMS

The WS_EX_CONTEXTHELP extended window style is not compatible with the WS_MINIMIZEBOX or WS_MAXIMIZEBOX styles. The context help icon isn't displayed on the caption as long as one or both of the minimize or maximize boxes is displayed. The same thing happens with dialog boxes using the DS_CONTEXTHELP and the WS_MINIMIZEBOX or WS_MAXIMIZEBOX styles.

Note that the window must have the WS_SYSMENU style.
