This feature is not functioning properly for me.

I have created statement groups before but this time
I have followed the instructions to the letter and it is not working.

I can start a new group,
I can select a file.
I CAN NOT tick any boxes in the Tabs listing.
I CAN NOT tick any boxes in the Department list either.

I used to be able to do this.

I am running the most current ledger, Windows 7. The program files and the data files are on the network.

Any suggestions?

Thank you
