MailWasher question

I use MailWasher as my spam catcher and have Thunderbird and Outlook Express as email clients. OE is not my default client but when I click on Process Mail MW always opens OE when I want it to open Thunderbird.

Can anyone help me in making the necessary changes?

Thanks!

 

Thanks for the response. The settings in OE are not my problem. The issue is that MailWasher is opening OE when I click on Process Mail. It does this even if OE is not open - MW opens it.

Any other suggestions?

BTW, where is the Thanks button?
