Lee,
I don't have any further suggestions at this point but I thought I'd
confirm that our application does use sound (and is not currently
crashing). I do almost nothing with applets thus I don't know if it's
an application vs applet problem you might be seeing.
Is it possible it's unique to your Win98 configuration? If you want to
send a copy (or test program) to me I'll run it on one of my testbed
machines (Win98 SE). What kind of a sound card do you have?
