I like the stick a lot. I did understand the statement about calibration on the Ultimarc page. However, I do remember forgetting this information and for some reason calibrating it via Windows, and forget whether that was before this issue occured. But I guess that was what caused it, because after resetting to default it's fine now. Although it only really affected Advancemame. (Also, I'm having trouble with it allowing the trackball to be used on trackball games, but this might be specific to how Advancemame handles various controls.)
Something else REALLY weird happened the other night, though. I was setting a map, and I think pressed 'download', and I got a run-time error box. Dumbly, I didn't 'snap' it. However, I noticed that when the box appeared, the whole mapper utility box underneath it had these black diagonal lines over it. (Similar to the red lines in image two, but over the whole mapper box.) Ultramap closed after I pressed 'okay', and the lines were gone when I restarted it, but when I clicked on the map menu, there was now no 4-way 45-degrees mode. (This one or the diagonals-only one work the same except that this one uses the default directions and turns them so you don't have to change the settings for each diagonal controls game after setting the map.)
So then I unplugged the stick and un-installed Ultramap. I re-plugged and re-installed and still the same deal. I restarted the computer and it's the same. The 4-way 45 degrees map is just, like, not there.
Also, there was a slight graphical error, as shown in image two. This was after the above actions, although restarting Ultramap seemed to make it go away.
I mean, I guess I could recreate the missing map. I'm just a very slight spooked that I have to.
