Jack,
Thanks for the reply. I noted my driver versions, but forgot to bring them
with me. I know the ASPI manager is version 1.01, and I think the CD-ROM
driver is version 1.46f (or something like that). I will post the exact
version numbers later tonight.
Thanks for the info about the T130 not really using an interrupt.
I am using a Microsoft Mouse (version 2.0) and the Microsoft Mouse driver
version 9.00, the very latest. I did try not loading the MS-DOS mouse driver,
and just using the Windows mouse driver (MOUSE.DRV version 9.0) – same problem.
I tried using the original Windows (for Workgroups) MOUSE.DRV – same problem.
I'm don't think that the mouse is "hogging the CPU" or interrupts as you
speculate. Here's why. First, the problem only seems to happen if I move my
mouse very slowly. Fast mouse movement all over my mouse pad doesn't seem to
cause the problem. But slow, slight, circular, movements always cause the
problem. Second, CD audio tools for Windows like Music Box really freak out.
The little "progress meter" that tells you how far into the song you are
actually starts flipping around, showing up at 0 then back at the proper time
index, and often disappearing entirely. Lastly, this will often eventually
hang Windows hard. Also, I have another machine at work (totally different
brands of everything) and CD audio works flawlessly under the exact same
version of Windows, Mouse and mouse drivers. If it were simply CPU or
interrupt hogging, none of the above would be true.
Any other thoughts or ideas would be appreciated Jack.
Take care,
James
