Thankyou all for your responses. The general opinion seems to be that 2007
just isn't worth it, and I'm happy to stay with 2003.

However, I will still have the crashing problem which occurs at least twice
per week, and sometimes several times in a day (like yesterday, which is why
it took me a while to respond to you all - I'm surprised you didn't hear me,
wherever you are on the planet).

I note that there are some upgrades for Ex 2003 available, but I've always
been loath to do an upgrade for fear of it screwing me completely, and
costing me days and days or repair work. My Ex 2003 is "as delivered" in
2003. How easy/safe is it to put through some upgrades please? Or should I
perhaps just repurchase Ex 2003 and install that (presuming that any current
release would have all the upgrades in it)? Regards, Brett.
