Hi Again: Error 623, as I understand it, means that the computer cannot find the local dialup number for the user's ISP. When I correct this in Win98SE I go to My Computer, click on Dialup Connections and go to Properties where I reenter the dialup number in the appropriate menu box. In Windows XP I am unable to duplicate this process. Instead, I must use a connection wizard which adds greatly to the time required to reenter the dialup number. Is there a quicker way to make this fix in WinXP? Is anyone aware of some imcompatibility between Eudora and WinXP which might cause this error to occur frequently?
