Please describe the problem:
I opened Gnumeric, and I created a spreadsheet. I typed simple characters into the spreadsheet.  a in one cell, b in another cell, etc.  Then I saved the spreadsheet and exited the Gnumeric application.  If I open the spreadsheet again by double clicking on the filename icon, there's no problem.  I can easily modify it or add cells.  But if I open the Gnumeric application, then open the spreadsheet by using the "file/open" command,  I can no longer enter data into the spreadsheet.  When I click on an empty cell and type something, it doesn't appear in the cell.

Steps to reproduce:
1. Open the Gnumeric application
2. Open a Gnumeric spreadsheet using 'file/open'
3. type something into an empty cell


Actual results:
Nothing appears in the cell

Expected results:
I would expect that the text I type appears in the cell

Does this happen every time?
yes

Other information:
I'm using Fedora 11 with the Gnumeric application installed from the add/remove programs menu
