Hi, I just got the Captivate, and I am having difficulty viewing attachments (Low kb excel spreadsheets and word documents). The weird thing is, it let me open one excel sheet once as what looked like an html instead of excel, which is fine as long as I can see it, but this hasn't happened since and it wasn't any particular thing different that I did. What should I do? Is it a bug with my specific phone? Thank you for your time!
