XP/Vantage

I've had a couple of test units on XP since it first came out. All
has been well with these. Recently I've upgraded a few more. 2 of
the 4 units keep switching out the Vantage.vtg with the
PlantFloor.vtg. They both have done it multiple times. Neither of
these units have ever had the PlantFloor.vtg on their system. Both
of these clients were upgraded from W98, as were all the rest. Has
anybody else encountered this issue?

Thanks,

Les Tingley
