It could very well be, hawtio has primarily been developed in Google chrome which really provides the best user experience. If you're on the 1.2.x version that was shipped with ActiveMQ it's likely there's some issues in there that have been ironed out since that release, the current 1.3.0 release works great on both Firefox and IE 10 & 11, and sort of okay on IE9. IE9 support still needs a bit of work really.
It should be possible to update your installed hawtio by replacing the embedded version, or you can always run it in a separate JVM alongside ActiveMQ and use the "Connect" tab to connect to ActiveMQ. Any further questions please feel free to post to the hawtio mailing list or issue tracker -> http://hawt.io/community/index.html Thanks!
