Dear Russ,
We try to duplicate this problem on a brand new computer but can not find the same behavior.
We realized some computers have this issue, but not occurs on all the computers. We hope we can diagnosis these computers but it is difficult to co-ordinate.
For now, we disable the Right mouse click on Poller to modify Poller property function.
Most of the Poller property attributes can be modifed on tool bar. For some attributes can not be modifed, user has to delete the poller and re-create the poller.
This change is part of the update of Version 1.88 which we release on June 14, 2006. Please download and test.
Thank you for your posting.
Winston
