FixUpDown is a RISC OS module that prevents keyboard keypresses being missed or “sticking”

The current version is 1.14 (30 Jun 2020) [32bit]

For historical reasons, many versions of RISC OS debounce keypresses. For some USB and PS2 keyboards this results in keys being missed, or “sticking” down and repeating.

This module ensures all keypresses last long enough to avoid being debounced.

It has proven to be useful to some users of RO3 and RO4. I don’t know if RO5 still has the same problem.


There is no API. Just install it in <Boot$ToBeLoaded> – !Boot...Choices.Boot.PreDesk.
