Hello Dierdre
If you are using the most current release of TBR (Version 6.6A dated 981030), then there is a 'fix' for displaying 4-digit years. It is available to all registered Users of this version/release of TBR.
You should be able to get these files from your Dealer, as he is a Softrak Business Partner, however, we are emailing you the fix, which should work with your earlier release of 6.6A as well.
Please watch for the email and follow the suggestions in there closely. This should allow you to see the whole year of the dates you are entering.
Hope this helps!
Regards,
Softrak Tech Support
