Create a dataset workflow doesn't work in IE7

Tested in IE7 - Not tried other versions of IE
- Complete step 1 of add dataset workflow
- Complete resource form (issue occurs whether you upload or link to a dataset)
- Click on "Next: Additional info"
- Page refreshes instead of going to additional info page. Looks as if resource information has been lost. 
- Dataset status is stuck at draft 
- If you then edit the dataset in a non-IE browser resource information is there and dataset can be finalised just by editing and saving.
