Windows 95 and Windows NT up to version 4.0 do not support help text for menus. Help text is only available in later versions of Windows. +When "ClearType" method is selected as the "method to smooth edges of +screen fonts" (in Display Properties, Appearance tab, under +"Effects"), there are various problems related to display of +characters: 2-pixel trace is left behind when moving overlays, bold +fonts can be hard to read, small portions of some characters could +appear chopped, etc. This happens because, under ClearType, +characters are drawn outside their advertised bounding box.
