Hi
I have used Access2 but it is so long ago I have forgotten the detail, and of course it was with correspondingly older versions of Windows.
But a few things puzzle me about your problem
Access is not case sensitive
Dates are held internally as a number, the dd/mm/yy or dd-mmm-yy etc is presentation (although you do have to have the correct locale set to avoid possible confusion between US style mm/dd/yy and UK style dd/mm/yy)
Could you give an example of where / how this is causing a problem?
Given that your user has WindowsXP, do they also have Office (and/or OutlookXP) installed with Access2 on same PC?, if yes, could it be that your problem is related to references to object libraries?, I presently have a problem (not with Access2 , but with Access97), which causes 'name#' type errors with dates, and appears to be related to a conflict between Access97 (Office97) object libraries adn OutlookXP (OfficeXP), but I have not managed to solve it as yet.
Just a thought, hope it helps.
