My home voicemail service (ooma) forwards voicemails to me as .wav attachments that I download through the Treos email. The link appears to show up properly but when I click on it it just brings up a small box with the play and stop buttons - but does not actually appear to be doing anything. The message file does not play.

Any suggestions or other programs I could use for this and/or directions on how to install it? I would like to be able to open up the email, click the link and have the message play. Dont care how simple or complex the program itself is.
