My lapotop has Vista 32 Home Premium and I have not encountered this issue.
Didn't Microsoft drop support for the VB6 libraries from Vista, though? I'm a C# guy so I have not tried any VB6 on this machine.
Microsoft supports the VB6 libraries on Vista for the lifetime of Vista or 5 years, which ever comes sooner. The question is whether or not Vista will last five years. At the rate it's going, I doubt it.
