This thread will keep track of issues regarding usability or bugs that we are aware of but cannot necessarily solve quickly, and any workarounds we have discovered.

Mobile: there are currently issues with many of the drop-down menus in Opera Mini. Please use Safari or Chrome, ideally.

Internet Explorer is currently showing issues with the responsive version of the site.

Please either use a different browser or select 'Vintage Opto' from the drop-down style chooser menu in the bottom left corner (this will give you a compatible "desktop" view on whichever device you choose).

Our developer has built in an auto-detect function that should now port old version IE users over to a useable version of the forum.
