Hi Ken,
Thanks for correcting the typo. I typed an demo program to present my case... :-) Sorry for the typo.
The bug is that two different user can share the same session. So for instance:
--- if I am userA on computer A
--- and you are userB on computer B
--- if userA is viewing ReportA
--- then userB although trying to view ReportB will see ReportA...
I have report name as a string property called strReportName that keeps track (kinda like a session variable) of the report name. But when userA selects the report userB will share that report name...
Hopefully that is a little more self-explanatory.

Not sure this is your problem, but I noticed a typo:
Private m_test As System.Int32 = Resquest.QueryString("TEST")
Should be Request
