Drop down Arrow not showing

[tgnarl]

I've made a spreadsheet using drop down validation lists. It works for all users except for one person. They are using Excel 2007 on a Windows 7 computer. They cannot see the arrow to show the list of options. The cell is not locked. If the user types in a valid entry, it works.
I've tried to save the file in xls format, vs. xlsx. Still no difference.

Anyone have a suggestion?

Um, no I didn't. The thing is, this is a standard file that is used by many people on the network. The idea is to open it, rename the file and then enter your data. So, while I could do that once, it would keep happening when opening that one file.

Two minutes later ...

I opened the file on the offenders computer, and found that there was no data validation of the problem cells (funny 'cuz it shows up on my computer). Anyway, I added the data validation and it all seems to work now.

Thanks for the suggestion.
