This web site works with:
    Internet Explorer (in Compatibility Mode only)
    Microsoft Edge (in Compatibility Mode only)
    Firefox

Else the menus at the top will be messed up.
Starting in mid-2022, inside the city's network, with a few exceptions, if you try to run Internet Explorer, it runs Edge instead. Unfortunately, after 30 days, Edge automatically reverts back to non-compatibility mode. Therefore nowadays, Firefox is probably your best bet in general.
Chrome seems to work sometimes, but mostly not. We don't know what makes the difference with it.
