no need to start a new thread. This is a known issue. A fix is ready and will become available with our SP3 release which is the first release that will officially support IE9. It should become available by the end of the week. You can download it from your Telerik account when it does.
Your previous issue with IE8 sounds very peculiar. Test Studio doesn't record clicks on Input control. Instead it directly feeds them parameters from the DOM when necessary. For instance if you navigate to Google and click on the search bar - nothing gets recorded. However, if you type some a "Set text" step is recorder. This is an action that directly communicates with the DOM - no click required. So that might explain the <input button/submit> part of your problem. However, I'm clueless as to why clicks on <a> elements wouldn't be recorder. If you still would like us to troubleshoot this then please provide as much info as possible - a Jing video, an application sample that demonstrates the issue etc.
Hope to hear from you soon!
