Getting (another) error and not sure why or how to fix it:

HttpContext.Current.Session.Abandon

Whoohffff...

Evidently I need to get a better handle on what the difference is between coding on a public *.vb class file, and the aspx.vb files.

Are the public variables in the *.vb file the same memory space for each session (span across all sessions)? Or are they still session specific?

Session specific

Check the help on variable scope to better understand.

The key to using the Session is by looking at what class it is from (HttpContext.Current). As you use it at page level, that context is available (i.e. there is a page there to serve to) whereas when you create you own class it isn't (much like how you couldn't use Response.Redirect).
