I just noticed a problem with the method PowerMail uses to display HTML mail in a Browser.: Your are able to display only one at a time.
Open more than one message and try to view them side-by-side in Safari. You will get this error message: A file error occurred File is busy Apparently, since PowerMail writes a temporary html file to disk, it can display only that temporary page. There is a way to work around it: Save each message as an HTML file. But it's an extra step for each document. Richard Hart
