    Before we go on , I forgot to say one thing (i am really embarassed)
I use an "A+ Mouse ADB" optical mouse.

When I discovered this, I booted on "Systems tools 1" floppy so I
had no INITs/CDEVs. The problem is reproducible in all applications
including the finder.

Something must have been changed in the way ADB devices are handled by
the system.

We also tried on a MacSE an the problem persist.  We also have
trackballs from Abaton and Kensington.  Both worked fine with 6.0.5.

   Does anybody knows what has been changed in ADB ?

   I will call MSC technologies (maker of A+ mouse ADB) when they
open to hear what they have to say.

PS. I forgot to mention the optical mouse because I never used the
	standard mouse more than a couple of weeks during the five
	years I owned and used macs. Again I apologize.
