Never buy an old version of an application unless you are a developer and must maintain separate testing environments. It is just a waste of your money. In fact, A2010 will soon be an "old" version. I think a new version of Office is coming out at the end of the year. Access is backward compatable and so it allows you to develop with A2010 and run in A2007 or even A2003 and earlier with the .mdb format. Your only problem is to avoid using newer features. If you are using the .mdb format, Access won't let you use features that are not backward compatable. Since 7 and 10 use the same file format, you have to be more careful yourself. If you "try out" a 10 feature, your database will never be able to run in 7 so you have to avoid that at all cost. Once you've set some internal switch, there is no way to unset it. You would need to create a new empty database and import all the "7" objects and make sure you don't take any "10's"
