I installed IE8 for several PCs in the office over the weekend, two PCs used today had the same symptoms, unstalled one and switched the other one to Firefox, problem disappeared for both. IE8 on my home vista x64 PC does not have the problem.
The reason I use x64 is to take advantage of 8Gb RAM.
Now 7110/14942 files left, seems like the backup will finish earlier than I thought. Graham should I wait for the back up to complete before trying FaxImport?
