GL Trial Balance - no decimals in debit/credit columns

Have a fresh install of GP 2010, SP3 on SQL 2008 R2.  The GL Trial Balance - Detail has shows no decimal places in the debit and credit columns of  the account detail.  I've done the following to try to resolve:

1. Checked currency decimal settings - 2 decimals

2. Checked if the GLTB is a modified report - it is not

3. Checked the Summary version of the report - decimals appear there

4. Run different settings in the Detail report - no difference

5. Exported the 4 existing modified reports and recreated the Reports.dic file - no joy

6. Googled (Bing'd) the issue - no results

I'm out of ideas.  Has anyone else seen this before or know what I else I should check?

Thanks!
