OK, so I have an A1200 with Blizzard 030 board and memory.  It works great, but I want to remove the accelerator and just use the A1200 bone stock.  When I pull the accelerator the right mouse button no longer works in Workbench.  I thought this might be an issue with the Workbench installation, but the same thing occurs when I boot with no startup-sequence and do LoadWB from an original WB disk.  Put the accelerator board back in and it works again.  Weirdest thing I have ever seen with an Amiga.  Has anyone ever heard of this before?  Are there any simple mouse button test programs out there.  I don't want to have to write some test code if it already exists.
Thanks!
