>My kids have installed some beta mail client; it has expired, I uninstalled it, and now I don't have a default mail client. If there's a mailto link, each browser thinks it should use its own email client - IE looks for OutLook, NS uses its own mailer.

OK, I bite the bullet and dived into MSDN... eventually found http://support.microsoft.com/support/kb/articles/Q175/8/62.ASP which then led to http://support.microsoft.com/support/kb/articles/Q154/3/59.ASP where it basically said that a mailto: link was a filetype, and should be set in the WExplorer/Tools/Folder Options. The grid there is way too small, but sorting by second column helps, I've found it, set {full path to netscp6.exe} /mailto:%1 as the command line, closed it, pulled up VFP 7, wrote a mailto: link in a comment line, and ctrl+clicked on it. Voila, there goes Netscape Mail Composition window, with proper address inserted.

Now there's a second chore, the MAPI shortcut in SendTo folder, which won't...
