I just created a JIRA wallboard. It runs fine on my own computer, but when I try to run it on another computer (same JIRA user, same browser, same OS) it doesn't run. Nor does it give me any errors to troubleshoot. It just shows a black screen with a blue "play" triangle. Am I missing some kind of browser plugin?
Browser: IE11
OS: Windows 8
JIRA Version: 6.3.15
