/* Min Width v1.1.3 by PVII-www.projectseven.com
 * http://www.projectseven.com/tutorials/css/minwidth/index.htm
 *
 * modified for readability and ability to limit application to
 * IE only so CSS min-width property may be used by compliant
 * browsers.
 *
 * NOTE: horizontal spacing (margins, padding, borders) set in
 *       % values may cause IE to crash when using this script.
 *
 * ALSO: padding, margins, and borders on parents of the element
 *       you specify may result in IE getting suck in an infinite
 *       loop. Please be sure to check your layout before you 
 *       publish it!
