I have an analysis of this really weird behaviour, and I've seen it in both
mac os [from v. 7.6.1 to 9.1] and debian linux. In my case (I have also seen
this on both a quadra 800 and this pmac 7500, btw) the when I move a window,
or click the scrollbar arrow, the cursor sometimes locks into "move mode",
requiring me to click again to unlock it. So my edumacated guess is that it
seems to be a bug in the ADB coding (on the ADB chip(s)) or hardware. It
certainly isn't software or os related.
my 2 cents,
eric
