Hi @Anonymous I believe this was incorrectly labeled as "solved", can you please clarify if you still have the issue?
We could verify that indeed clicking on the "Play" button it opens in a non-resizeable window on IE.
Two ways to mitigate the problem:
1) if you copy the url of the page and paste it in a regular IE tab it will open correctly. So, that should unblock you.
OR
2) IE, however, has a setting to always open pop-ups as new tabs.
This what you need to do (assuming your IE is in english).
Go to:
Tools (the gear icon on top right of IE screen) -> Internet Options
In the Internet Options Menu, stay on "General" Tab and click on button "Tabs".
on the Tabbed Browsing Settings menu, on the "When a pop-up is encountered" section, pick "Always open pop-ups in a new tab".
Naturally, this may have different implications if your company makes a lot of use of pop-ups. Please pick whichever works better for you.
