Problems with New Mailing

[blakey]

Hello - we have installed OEMM and all there, but there is a problem with the Mailings section.

Whenever we click on New Mailings, and select Normal, the programme just sticks (it shows the waiting bar but nothing else). It appears to work with Wizard, provided we havent clicked on Normal first.

Any suggestions? Is this something fairly obvious?

Advice gratefully received..
