On 24 January 2017, Mozilla released Firefox 51, and this update is being deployed automatically to computers using Firefox. We have recently been made aware that this browser update causes a problem when completing exams on the IAQG Training platform when on Windows and using a Hi-DPI display configuration.
If you are using a Hi-DPI display configuration, you will receive a notice with a yellow bar at the top of your window upon entering the training or assessment.
Impacted Configurations: Firefox 51 or newer, on Windows 7 or newer, on a Hi-DPI display configuration (also known as “DPI Scaling”).
Issue: When clicking on the answers for multiple choice questions, the associated checkbox or radio button may not always activate or deactivate. In some cases, the checkbox for a previous answer may activate/deactivate, or a different radio button than the one you intended to select may become selected.
Workarounds:
- Use a different web browser for the time being, such as Google Chrome, Internet Explorer, or Microsoft Edge.
- Access your Display Settings, and reduce the “Change the size of text, apps, and other items” setting to 100%. (On Windows 7, this option can be found under “Display” in the Control Panel, and is titled “Make it easier to read what’s on your screen.”)
We are working to further diagnose this issue that was introduced in Firefox 51 and newer, and hope that we can provide an update to our training software as soon as possible that will bypass the problem.
UPDATE: We have confirmed that this issue remains a problem in Firefox 52, and have updated this news post accordingly.
