Thanks.  Using System Mailer did not help, but while looking for it I found that the web browser commandline setting was incorrect.  It pointed to the Program Files folder instead of Program Files (x86) that holds Mozilla Firefox.  I changed that and it fixed the hyperlink problem.

After moving everything to a new computer, Pegasus 4.6 is working just fine except that clicking on a hyperlink that should trigger my Firefox browser does nothing.  If I copy the URL into the browser location line, it works fine.  This should happen automatically by clicking on the hyperlink, but id does not.  I did not have this problem on my older computer.  It ran under Windows 7 Home edition, at 32-bit.  The new one runs under Windows 7 Pro at 64-bit.  Has anyone else had this problem?

Copy to a new computer is not the same as running the v4.63 installer exe file and then also using  the System Mailer button in the Tools, Options entries. The installer does more than just copy files to the computer. If you can't find the System Mailer button then go to win explorer and the c:\pmail\programs location and run setpmdefault.exe to set System Mailer and then in win7 check Start, Default programs and associations to make sure the OS settings are correctly pointing to Pegasus Mail and Wsendto. Sometimes during install of other programs or  updates the associations and protocols get reset and must be reset again to point to Pegasus Mail entries. When that happens it is not any Pegasus Mail problem but is one of the OS system or the installer routines of other software setting things to point to themselves instead of to your choices.
