Eudora disconnects me from internet

[luv2rallye]

I use Eudora 6.1 email program on XP (with all latest updates). When I'm connected and Eudora is running and I'm not doing anything with any browser (I.E. browser is up but I'm just using Eudora to read or compose email), it disconnects me after about 20 minutes with a message stating it will disconnect due to network inactivity. I do not leave mail on the server but have Eudora download it when launched (and when told to check mail). I have both Eudora's "Network Open Timeout" and "Network Timeout After" set at 3000 seconds but I can change these to any value and it makes no difference. I can force Eudora to check mail (to get network activity) as often as I want but it still kicks me off after 20 minutes. The problem goes away if I close Eudora.

I'm tired of being kicked off every time I compose a long email or take extra time to read emails or just leaving Eudora up more than 20 minutes. This problem has always been present since day 1 six years ago. I've contacted Netzero (my ISP) and they said it's not their problem and to contact Eudora. Eudora won't provide technical help to those not in "paid" mode (I'm in "sponsored" mode) so they won't even talk to me or accept emails (I've tried). Any ideas?
