Learn@UW has reported an issue in D2L with the latest version of the Chrome browser (version 30). Any frame inside an IFRAME that gets dynamically resized may not render correctly causing frame sizes to be too small to work with effectively.
Affected areas in D2L include Discussions and the Question Library. This issue should be corrected in Chrome version 32. Until then, the current workaround is as follows:
On screens where there is a visible frame divider, move the divider to restore a normal view. Where there is no visible frame divider, grab the side of the entire browser window and make the window narrower until the content comes into view. You may then resize the window as desired.
If you have any additional questions or concerns, please contact UW-W D2L Support.
