Outlook 2003 and mail alert question

[Salamander 2]

I have Outlook 2003. There is an option for showing a mail alert, which shows up near the right hand bottom of the desktop. However, it only shows for 20 seconds at the maximum. Does anyone know of a way in Outlook to set it so the message alert stays visible until you take action?

Also, has anyone heard of the software "MailAlert"?
