I agree with this. I recently added a feature to DPScan for Windows that lets you turn off warnings. I will change the filter.

What causes the warnings -- is this expected behaviour with TIFF files? I find I can save the pictures (line art) out of OPW as Draw files and get round the "warnings" problem, but the files are just as big (if not bigger) as the original TIFFs.

The second problem is do do with memory. I have an OPW document with about 20 TIFF pictures. Current file size is around 300 Mb.

Interesting. How much memory does your machine have - physical and virtual?

1GB physical, 1535 MB virtual (set by Win XP) -- should I increase it? And if so, by how much? From what you say below, if I increase it to 3GB, as things stand OPW will only be able to use up to 2GB (?)

There is another issue which is address space, on 32bit windows, typically an application can have only 2GB of address space. So even if your swop file is 4GB you will still hit this limit.

Memory and address space use is shared between all open documents and things like the clipboard, as well as other workspace. OPW also holds documents in a single block of memory - in other words fragmentation of the programs 2GB space may reduce what can actually be used.

It is possible to configure Windows to run with a 3GB address space for each application and this is becoming more common with the larger files around these days. 

Is there a website that explains how to do this?

Long term solution of course is 64 bit Windows.

In an ideal world, perhaps ... But does it do what it says on the box? 32-bit Windows is supposed to address 4GB of physical memory and my motherboard has a capacity of 3GB, but if I install more than 1GB the whole system collapses :(
