BCM Custom date field format not working

Hi,

I have found that the date format on a custom date field in BCM 2010 does not work for me. I am running Win7 32bit, Office and BCM 2010. I am in the UK so the regional settings are set to UK. I have created a custom date field for Accounts, however whatever I pick from the Format drop-down on the Edit Field dialog box, I get the same date format on the form: Day DD/MM/YYY. If I pick a date and time format I get the same date format plus a time drop-down. This is annoying as the field is used to select a month, rather than a date so I wanted to use the MM/YYYY format or Month-YY.

Thanks
