Hi,

After trying different things and wasting lots of time I notice the
following:
If I have my.yahoo.com as my home page  AND I am logged in to my AT&T
yahoo account then applets DO NOT work.  If I have a blank page as my
home page then applets do work and I can visit my.yahoo.com without
destroying this ability. If I erase cookies so Yahoo does not know who I
am then I can use this as my home page and applets still work.

So it seems that AT&T is using some sort of Java code that screws things
up for any other applets.

Strange.
