[BC] Visual Basic ver 6 and MScomm

[Robert Meuser]

A few things.  Certain applications need to be re-compiled while working 
under the target OS. Another point is why are you attempting to make a 
new application work on unsupported OSs? Any decent sized IT operation 
will no longer permit win 98 and NT 4 to be on their network to begin 
with.  I would not loose a lot of sleep over something not working with 
Win 98. As time goes on, most things will not work under Win 98.
