// Workaround for Windows MSIE 1-6 not supporting CSS2 "position: fixed":
// exploits the fact that WinIE appears to render "position: absolute" as fixed within viewport.
// Thereforeset create var "positionfixed" initially "fixed" but set to "absolute" if browser is Win MSIE 1-6,
// and use this in "shownote" function to reset element style.position.
// "hidenote" has short delay.
