Since 1st February 2020, Quadzu is no longer compatible with Microsoft Internet Explorer, and while some features will work, you will encounter problems and slow performance when using any version of Microsoft Internet Explorer.
Many of the advanced features used in Quadzu weren't even possible when the last major version of Internet Explorer was released in 2013, so building Quadzu to be compatible with it means everyone misses out on important features, enhanced security and improved performance.
If you have a modern PC running Windows 10, Microsoft Edge is probably already installed and offers full support for Quadzu. Alternatively, you can download a range of modern web browsers for free.
