Cell highlighting Issue

[jasonk916]

I'm having this problem with a few of the documents I use that have been converted from microsoft 2003 to 2007. For whatever reason, sometimes when I highlight a cell, the 4-5 cells above or below it in the same column also become highlighted. Other times, if I click around furiously enough, I can get just the cell I want. This might be more of an occurrence with the embedded tables I use, as I havent yet discovered an instance of it occurring on the spreadsheet itself, but it is still very annoying to try to work around. Does anyone know of a reason why this might occur?
