Printers help error

Playing with Steve Fryatt’s ‘Float’ and setting ‘Show help over iconbar’, Printers errors with ‘Internal error: abort on data transfer at &FC19711C (&80000002) @2490’. Printers appears to remain functional on clearing the error message.

Float 1.01, Printers 1.89 (28-Feb-18), ROS 5.29 (16-Feb-21), BB -xM

Hmm, just tried built in ‘Help’. Same error.

Edit: Only happens on BB -xM, fine on RPi 4B.
