Thanks, Jerndl - Here is what I have done this afternoon and some further comment on what is happening. After I do an update, it appears that the first click to scroll (using the up, down, left, right command) will bring one single move, then nothing more and from then on 2 clicks are necessary to get the thing to react. The scoller will also work fine if you hold it down (fast scroll). It is just single ups and downs it will not handle.
Here is what I did based on all your kind recommendations:
Did a learning using the normal instead of raw commands. No change.
Keeping this setting, I then fooled with the repeats, 3 (default), then 5, then 0. No help. Then loaded in new similar device from same manufacturer and tried to see how it worked. It did the same thing on the up, down, left, right control. So normal, raw and manufacturers commands all seem to bring the same issue.
I then went back to my original device and changed the interkey delay from 500 to 100. No help. I then moved the interdevice key, previously at 100 to 0. No help.
That was my fun hour fellas. I am thinking of rebooting the unit out the window, but maybe some of my new info will bring a light bulb.
Again, much appreciate the help from all.
