Which Version Of Access To Use ?

Hello All

I have a database which is use at busy times to run the delivery side of our Floristry business. The orders are entered,assigned to a delivery area, address labels printed. When it comes to delivery day orders are selected from the list ticked off then printed a make a list for the driver.

It was built using Access 97 when it first came out. Since then the software was upgraded to Access 2000 many mods have been made each year to improve the performance and the number of things it can do. It now has about 15 tables and a lot of queries.
Not being an expert with Access a lot of the design has been on a trial and error basis. Put it another way the main form has many hidden fields to make things work behind the scenes. But it does most of what I want it to.
I have now go to the point where the main query is saying that I can't add any more features because I have to many fields in it.

So the time has come to look at re building it for a number of reasons.

1. It is a stand alone database on one Pc.......... I would like to have it on a network to 3 or 4 Pc's around the shop.
2. Some of it needs to be redesigned to take out my ( it might not be the way a designer would it but it does work) type bits.
3 I would like to be able to use the system for all orders received on a day to day basis. So it will need to be used by other people.


My question today is
Should I be looking to rebuilt it using Access 2003 + the extra software so that i can run it on more than one PC.

Or would it be better to wait few months till Acess 2007 comes out and start from scratch.


thanks

Kevin.
