DU and Windows9x

[Justin Walsh]

Hi.
For many months I have had no problems.
DU is really great. My netgear RT 314 works fine.
What does DU do with the windows\cookies\index.dat file?
I noticed that it loads index.dat at installation time.
So too does my Bigpond.Net cable install program load index.dat
All of a sudden I'm getting the Windows warning:
"cannot find data" when doing attach and even email send.
Ive completely unbolted IE, I don't see why it needs index.dat.
I use Firefox.
Confused
Regards and thanks DU for a great product
Justin
