For some blasted reason the send button on Mail keeps getting greyed out. I try resetting from time machine backups. It will work for a few messages then become greyed out again. When I used the Connection Doctor everything checks out as fine. My SMTP information is correct. As it has always worked in the past, works in Outlook, works in Entourage and cross checks as correct by multiple online sources and the ISP's customer service. I have also repaired permissions. Why would this button ever be designed to grey out in the first place? An error message after clicking would be better then a button that give no information at all. Unfortunately this is a customers computer so I can't just swing by to check some more. The above listed steps are ones I went through before performing a time machine restore. Which worked for a while then the same problem occurred. Another Time Machine restore fixed it. Now the customer is having the same problem so I am trying to find another solution.
