I found today what appears to be a bug with the Shading tool in Microsoft Word 2010 when dealing with tables. The build of Microsoft Word I'm using is 14.0.5123.5000.
I'm running Windows 7 SP1 Enterprise x64. My installation of Office 2010 is 32bit.
My word document I'm working on is in docx format.
The problem comes around selecting an existing colour from a table.
Here i have my cursor in a light blue table:
To get the RGB color code I go to "Shading" --> "More Colors".
However its coming up with my current color as black (see bottom right). It comes up as black not light blue!
If I click OK it will make my cell black.
Now I undo my change (CTRL + Z).
Now I go back to "Shading" --> "More Colors"
My light blue color is now coming up correctly.
If I close my word document and re-open it, the problem does not re-occur.
If I log off my session and log back in, the problem re-occurs.
I reported this bug to Microsoft on the following forum thread:
