>> So, if the users of Julian's application run Excel 2003 he should develop the application on 2003. <<
Thank you for pointing out that which had not occured to me....that Julian's work might be distributed to other users who lacked the more up to date version.
In that case, creating in the earlier format is eminently sensible.
I should say that my face is red, in that I have relevant experience in a small office that had workstations with differing versions of MS Publisher and have been faced with portability issues when opening a document prepared on one station at a different one. In mitigation, its probably been a couple of years since that was the case, as upgrades have brought the different workstations pretty much into harmony.
