I set the shortcut to pmail.exe as the application. When setting the

E-mail app, there is a blank field in the setup screen of this part of

Opera which says "parameter". What do I put in that field so that

clicking on the E-mail link will put the desired address and Pegasus

together in harmony ?

Take this with a grain of salt since I quit using Opera quite some time back as too slow and non-standard in my particular use. 

Are you talking about the mailto: type URLs?  If so the program should be drive:\path\wsendto.exe and the parameter %1.  The wsendto.exe is in the WinPMail program directory.  That said, by default when you install WinPMail it sets the mailto: protocol to wsendto.exe and I would expect that Opera should be able to pick this up from the OS.

I'm using Opera.

I came across a page that has E-mail links

They did it in some sort of Flash app

Presumably ? To avoid spam-bot harvesters ??

Whatever, whatever, I set the shortcut to pmail.exe as the application. When setting the E-mail app, there is a blank field in the setup screen of this part of Opera which says "parameter".
