Dear colleagues,
I have issue with rendering reports in Internet Explorer 11 or higher. The SSRS 2014 is running in Native mode. Comboboxes (multiple values) are not sizable unlike SSRS 2008 R2. If you don't select value and click outside, the selection freezes and you cannot select value from this combobox until you finished the same operation in another combobox. The report users are frustrated. In other browsers like Firefox the comboboxes are sizable like in SSRS 2008 R2 and selection doesn't freezing. Switching browser to compatibility mode in IE doesn't help.
Thank you for any tip how to resolve it.
