In the continuing saga of the "minor but irritating" Thinkpad problems, may
I present my mwave annoyance. At least, I think it's mwave.

Relatively frequently (about once or twice a week) the computer crashes in
the following manner. I can be working away (on Excel, Word, WebEdit or
Photoshop usually - I don't think the application matters), sometimes
reading what I've just written (i.e. no keyboard or mouse activity), other
times actively typing, and the speakers suddenly start to emit a long,
sustained note. It's always the same frequency. As soon as this happens,
samples are no longer played. In fact, when the computer attempts to play a
sample it pauses for about 30 seconds. So, I try and close a program, and
everything locks up for a while as it attempts to play the "close program"
wave. Usually, I can close one program and any others running then lock up.
Hitting CTRL+ALT+DEL brings up the task manager window (eventually) which
tells me most things are [not responding]. Sometimes the task manager shows
me that "mmwave", "rnaapp", "mwsw95" or "POp95" are not responding - or at
least present when they are normally absent. Is one of these the culprit?

I can never close down Win95 normally from this state, eventually being
told that the whole system has stopped responding. A soft reset is required
(sometimes a hard one). When Win95 reloads, it starts to play the
monotonous note again, but this disappears shortly before it plays the
"Start Win95" sample.

I hope I've decribed the problem reasonably well. Does anyone have any idea
what's going on?
