On our Orion NPM Home/Summary dashboard, we have the "Search for Nodes" resource added. When we type something in the "Find" field and click "Search", it returns the results just fine. Pressing ENTER (keyboard), though, clears out the Events resource we have on the same dashboard/page, and doesn't give results (most of the time).
This is probably the answer/solution, but this behavior seems to be limited to IE9. Firefox 4 captures the keystroke and returns results just fine.
Feel free to mark as answered, as long as this is on the bug list for fixing in the release that supports IE9. Thanks.
Chris, yep this is a known bug. Works fine in FF as you stated, but the enter key is not captured correctly in IE. We have a defect logged into the system for us to fix in a future release.
