excel email attachments
Just tried to read one for the first time (really wish screen rotation would work on those).
Here's an issue I haven't seen mentioned elsewhere. The spreadsheet has multiple worksheets (tabs). The viewer shows the tabs on the top (instead of bottom), but they are TINY! You have to zoom way in to tap them. And the leftmost tab is highlighted even after you select a different tab (selecting other tabs DOES display the appropriate sheet, however).
Other than that, the formatting and everything was pretty good, but I did see some glitches (missing borders, text a little too big, etc.) Some of the formatting problems could have been caused by my using "nonstandard" fonts.
