For some reason with v184.108.40.206a and higher, scrolling to disk numbers over 39 (using indexed mode) does not work. It simply wraps around to 000 again.
The new "Files Browser : All Files/Folders with the hidden attribute set are not shown anymore... (Hide Windows/MAC system folders)" seems to be the cause somehow. I don't use that feature, so I'm not sure how well it functions.
I thought this might have been a file naming issue where DSKA0040 was missing, but that cannot be because 220.127.116.11a (and prior) are working successfully.
v18.104.22.168a appears to be perfectly stable and the slow button repeat time is solved, so I'm very satisfied! Although I'll repeat my request for 0.5s disk change to be added as a parameter 0 in Menu 5 -- just because it *might* be useful
