Here's what I could find RE: supported browsers:
Supported Browsers
Jive works with most current web browsers. Note that if you need to use Content Editor features such as cut and paste, script access to the Clipboard should not be disabled. Minimum screen resolution: 1024 x 768. Results may vary if you use zoom to adjust your view to levels other than 100%.
- Microsoft Internet Explorer 8, 9, 10, and 11. Note that Internet Explorer 8 will not be supported in Jive 8. Note: Compatibility mode with earlier versions is not supported. Internet Explorer 11 is supported in Jive 7.0.1 and higher.
- Apple Safari 5, 5.1, 6.0 (on Macs only)
- Mobile Safari with iOS7+. (Note that a browser-independent native iOS Jive app is also available from the App Store.)
- Mozilla Firefox*
- Google Chrome*
* The Google Chrome and Mozilla Firefox browsers are released frequently. Jive Software makes every effort to test and support the latest version.
Can you produce these issues from the video 100% of the time with IE9? I'll open a case with Jive support, just want to make sure I have all the information.
