Windows 7 Insufficient resources

[Flupsie]

Sometimes when I Open up an Excel attachment in outlook a message comes up "insufficient resources" I am using Windows 7 operating system & Excel 2007. The same problem occurs when I have several Excel files open and run a macro

I am using an Intel TM2 Duo CPU 2.93GHz and have 4GB of RAM

How do I overcome this problem?

This may take time to analyse but the first think I'd check is add-ins - in particular Adobe - they are infamous for eating up resources and it is very unlikely you are using them

All the add-ins have been disabled. Adode is used as a seperate application and is not added in on the office package
