John,

Thanks for all the work but no, it don't work. You was right, of course, about the file name but a search for 'mudcat[' don't work either. (Sometimes it's mudcat[2 or mudcat[3)

Nothing is placed in C:\Documents and Settings\username\Local Settings\Temporary Internet Files unless I use IE or something else that depends on it (eg, RealPlay, I think). Generally I vastly prefer Firefox.

Yes, I'm pretty sure Firefox keeps cookies in a separate, single cookie file. C:\Documents and Settings\username\Application Data\Mozilla\Firefox\Profiles\(random number).default\cookies.txt but no 'mudcat' text seems to enter the file. Other useful cookie names are in there, though.

Netscape definately uster do that. Yes, I've set Firefox to "Allow" (ie, permanent, not session.) and cookies are specifically not to be deleted if I should ask to Clear Private Data on exit. (I rarely do that anyway.)

Don't know what else to look for.
