Date Selector Library

Hello Robert,

I've a form (powermail extended to use rlmp_dateselectlib) with 4 select boxes. 3 of them get covered by the date selector.
The select boxes get hidden when the date selector pops up. After closing the date selector the select boxes are still hidden.
After a while of debugging I've found, that in the case of Safari the Function getVisib() returns ''. Changing value = ''; to value = 'visible'; fixes the problem for me.
I didn't find any side effects yet.

      if (!value) {
        if (document.defaultView && typeof (document.defaultView.getComputedStyle) == "function") { // Gecko, W3C
          if (!tx_rlmpdateselectlib_calendar.is_khtml) {
            value = document.defaultView.
              getComputedStyle(obj, "").getPropertyValue("visibility");
          }
          else {
-           value = '';
+           value = 'visible';

If you need any further information, please feel free to contact me!
