How to Change Default Database in Vista?

[J-Mac]

I run UR on a Windows XP Pro machine and a Vista Ultimate notebook.

On the Windows XP Pro desktop computer, UR starts w/ Windows and always starts with the last database that was open. However on the Vista notebook, UR always opens with the first database I created after installation; never with the last open database.

Anyone have any idea why the behavior is different between XP and Vista? And what is the best way to assure that UR opens with the last database used? Help file says to create a shortcut to the database in the Startup folder, but I am wondering if there is a way to do this from within the UR Options.

Also one other database question (one for which I will probably not like the answer!):

Is there a halfway reasonable way to use the same database on my desktop and notebook computers? Or, if not, to synchronize the data from each? Hopefully without going through an export/import sequence each time - that's not a reasonable method IMO.

Thanks!
