[galaxy-user] Datasets no longer acessible in my history

Dear All - Since Friday I can no longer click on datasets in my history. The "Display in browser", "Edit attributes" and "Delete" are still clickable but I cannot select the dataset to see content or download the data in my history pane. I can only do this if I click "Show Structure" from my history options. Then my history is clickable in the main window. This is rather time consuming. Have I checked an option for this by mistake and if so how do I get my access in my history back? Many thanks in advance for any help and apologies for cross posting.
