Thumb driver enumeration might be different on each machine -- how does Thunderbird find its profile?
The .ini file for Thunderbird looks like this on machine #1.
[ThunderbirdPortableSettings]
AgreedToLicense=YES
LastProfileDirectory=F:\PortableApps\ThunderbirdPortable\Data\profile
The USB drive enumeration might be different on another machine.
Does this get handled in some way?
