Known issues

After picking a colour with the eyedropper in a colour box's picker, the mouse wheel does nothing on the page. The 3D views and the strat planner will not zoom, and the page will not scroll. Clicking the page does not bring it back.

Where	Anywhere with a colour box: the build renderer, the part pages' paint and the strat planner.
Seen in	Chrome on Windows. Other browsers built on Chrome, such as Edge, may do the same.
Way round	Switch to another window and back (Alt+Tab twice) and the wheel works again. Or pick colours with the picker's sliders, swatches or hex box instead of the eyedropper.
Status	A bug in the browser's own colour picker; the site cannot fix it.

The site is laid out for desktops and tablets. On a phone, pages may be cramped and some controls hard to reach.

Where	Every page.
Seen in	Any phone.
Way round	Use a tablet or a computer.
Status	By choice: the tools are built for bigger screens.
