I have been experimenting with derivitives of Allegro example program
ex17.c.  I wrote a set of c routines which allow for concatenating wav
files.  The logic is a little rough but they worked fine.

Now I am experiencing a different kind of problem, perhaps you can
diagnose the problem.  When I try to run the example program ex17.exe
from within a DOS window (Win95, P166, 128MB), I get the following
message:

This applicaton attempted to access a device that is being used by
another application.  If you continue running this application it might
cause your system to lock up.   Type Y or press ENTER to continue
running the  application.  Type N to end this application.  Press Y for
Yes of N for No:

Have you ever encountered this type of behavior?

I have recently installed CoolEdit to create some sound samples, but
since that time, the example ex17.exe and my derivitives are generating
the above system warning.  I don't know if there is any connection
between installing CoolEdit and the system message, but maybe?  If I
respond Y to the above warning, the programs run, but I don't get any
sound.

I have tried powering down the computer, then immediately trying
ex17.exe but still get no sound.  Aparently the sound card is being
grabbed by some application at startup but I don't have a clue as to
where to start in tracking down the culprit!

Dazed and Confused!?!
