OK, user error on my part. I found the solution in the global settings, per your input. Thank you! Heh, I was looking for some sort of settings in the software as opposed to scrolling trough the menu pages on the H90.
The only other issue is that the H90 – with my quick tweaks to the settings to try to quickly resolve this – can not discern between an on/off and a momentary switch… but, I will check the settings on the H90 a bit more in depth when I have time to fix this.
