Hi - I have an Excel 2007 speadsheet which is Not Responding (hanging) with a pale grey / white screen. This follows the simplest of tasks which is saving following cutting and pasting a formatted cell (coloured fill) from one to the next, or when inserting a column and then saving.

This is a problem which has just started following Excel 2007 getting confused due to trying to perform a task too quickly. Now the problem persists.

System Spec
Excel 2007 running on Windows 7 Home Premium Ed, running on Parallel Desktop on MAC.

I read somewhere that it could be due to:
1. Basically there can be a conflict between the 64 windows and the 32 bit Office suite. The only clues I really saw as he wiz-banged around the screen were the use of an Office Hybrid 2007 file and him changing the "XLSSTART" folder to "XLSSTARTOLD" .
2. Clipboard causing the problem possibly solved by a change from DDE Server to Active-X Control

Regardless of whether it is due to the above, I need a solution and step-by-stp idiots guide how to implement.

Help would be greatly appreciated.

David
