I do indeed have 2003 and haven't upgraded precisely because I find it works perfectly. I operate a "If it ain't broke..." policy to I.T. I hope I'll be able to keep 2003 on my main machine. My problem however has become running certain spreadsheets with macros created in later versions of Excel - it's obviously time for an upgrade.
Yes, some advanced features may be incompatible.
But, I must admit, I use always O2003 if possible, the new Office GUI style (ribbon menu) is terribly counterproductive...
I realise this may be a dumb question but if you run the two in parallel, do files automatically open in the version they were created/last saved in?
It's not a dumb question because at least two scenarios are possible.
I.e. in your case, the last used version will be invoked but it's annoying 'cause the newest Office versions detect changes and reregister their components, it may take few minutes.
It's possibly to hack it using the registry editor. see e.g. http://support.microsoft.com/kb/2121447 but the results may be somehow unpredictable and it's better to avoid it.
It's better to have two separate machines.
