My ZM is working fine, I set it up ages ago, but I just found out that I can't edit anything that requires popups

On the main page 'refresh' works, 'add new monitor' does nothing, 'filters' does nothing when I click on it.
but I can find the URL and go to it directly
https://server/zm/index.php?view=events ... [1][val]=3#

The html shows:
<input type="button" value="Add New Monitor" onclick="createPopup( '?view=monitor', 'zmMonitor0', 'monitor' ); return( false );"/> <input type="button" value="Filters" onclick="createPopup( '?view=filter&filter[terms][0][attr]=DateTime&filter[terms][0][op]=%3c&filter[terms][0][val]=now', 'zmFilter', 'filter' ); return( false );"/> </td>

I don't think I have a popup blocker, it fails with 2 chrome browsers and with firefox (I get no popup warnings)

Is it a problem with the html, or are my 3 browsers preventing the createpopup from working?
Javascript console shows:
Uncaught TypeError: undefined is not a function
skin.js:82getPopupSize
skin.js:142createPopup
(index):85onclick

Thanks,
Marc

I'm still stuck there, am I the only one with this error?
