Question: Will v4.0 run on my laptop?
You must have at least a Pentium 166 laptop with 32Mb of memory. This is a Windows application, and as such it competes with all the other resource intensive things associated with Windows. More memory is HIGHLY recommended (at least 64Mb) and a faster processor (200MHz or more) can really help as well. Windows brings it's own baggage with it!
This is one of those cases where you need a relatively decent laptop.
We've found a couple of sources for good quality used laptops, such as :
* DPV, Inc.
* tel 914-923-5100
* fax 707-202-0400
They sell refurbed laptops. We bought a "lab rat" PII300 Dell with 64Mb of memory for about $350 shipped. They had a bunch of inventory and the one we received look like brand new!
HTH,
