+			// positioned in IE7. It also happens that it remains sticky and user cannot
+			// scroll down/up to reveal dialog's content below/above the viewport; this is
+			// cumbersome.
+			// The only way to fix this is to move mouse out of the browser and
+			// go back to see that dialog position is automagically fixed. No events,
+			// no style change - pure magic. This is a IE7 rendering issue, which can be
+			// fixed with dummy style redraw on each move.
