Andy,
We've just implemented EWP for our upcoming exam season, thanks for writing a free program for this purpose.
Do you think it's possible to include the %REMOVABLE% variable (taken from AppLocker) when setting default save paths? I've currently set it to D:\, but that relies on the lack of a CD-ROM drive in the exams PCs. Most of the time the system will assign it to D and it works seamlessly, the other times the user gets hit with a couple of C drive restriction pop-ups and then has to browse to the right drive.
Regards,
Gareth
