Currency column rounds up... sometimes

Hi, in a SharePoint list, I have currency columns that seem to work fine, until it starts to round up or down the cents. I then have to refresh the page, try again, it might work for a few entries than starts doing it again.

I saw that there was an old discussion about this problem but it "resolved itself". Is this a continuing bug? Is there something that I can do to stop it from doing this? The cents information is gone after this round up or down. So I have to re-enter the number hoping that it works. 

Thanks for your insights.
