Hello,
in this example http://dojo.telerik.com/aJUKiZuB I reproduced a problem with the dropdown. When you open it and directly close it (before its opened) by clicking i.e. below, there is a faulty animation, where the dropdown animation container jumps to a wrong position. With jQuery 1 its working fine. Same problem seems to be on multiselect (maybe also on other widgets?).
Regards
Jan
