The very old version of prototype (18.104.22.168) from 2008 has problems with the changed event handling of IE9.
There are several solutions to that, described e.g. here http://mandagreen.com/prototype-1-6-event-stop-ie9-quick-patch/:
- Update to prototype 1.7, which is a no-go for at least 4.7
- run the backend in IE8 compat mode like 4.5, which also is a no-go
- patch prototype sources, also not an option for the backend usage
- not using prototype event handling for the click events in the menu, but using the native ones. Shouldn't be there more broken modules in IE9 then?
Please test the attached patch (applies to 4.7 and 6.0). I went for option 4. and removed the Event.observe code and replaced it with onclick calls.
IE9 and IE10 in my virtual machines sent out the Ajax request and cleared the cache successfully.
