Recovering from major crash, had to reload XP and Office 2003, etc. Now
when I open an Excel workbook, I get a small triangular mark in the upper
left-hand corner of some cells. Apparently to do with formatting. Anyway,
try as I might I can't find the right box to click to get rid of it.

Been here before but I don't remember what to do. Appreciate any
suggestions

Thx
Dave
