+*[IgnoreSizeHints]* {'bool'}::
+    Some Applications restrict the aspect ratio, minimum or maximum size of
+    windows. Setting this key "yes" will make fluxbox ignore those constraints.

 Position the application at a particular spot. By default the upper-left corner
 is placed at screen coordinates ('X','Y'). If you specify an 'anchor', say
