Ive been useing a database for about 10 years with no problems. Recently the combo boxes on some of the forms appear blank when the 'pull down' appears. The version of Access is 2003 and i'm wondering is it a problem with the new operating system recently installed (XP 64 bit) which may be a problem. A colloegue has just had the same problem when an update was installed on his computer. Has anybody seen this before?
