Date Formatting in Excel causing problems

OK I know the solution to this problem is to NOT use a .CSV file but to use a .TXT file and use the "OPENTEXT" function to make sure date fields don't get switched around, e.g. 11th September becomes 9th November, and I also know I started a thread on this ages ago which I resolved.
I also know what values to use when specifying each column in the output.

What I DO want to do however, is find out conclusively (if possible), that the problem relates to the Service Pack and/or version of Windows being run at the time.

Can anyone confirm this ?
