Dan, Thanks for your reply ... Glad to be helpful on the one tidbit I uncovered!
Looks like your conclusion is the same as mine: the object variables are readable within the handler functions, but they are not writeable. Hence your use of the global variables ... That seems to be the only workaround. I'm convinced this has to be a bug ... Because what good is a "contained" class if you've got to interact with global variables in order to get the job done? Theoretically speaking, how do you know that you're not stepping on the toes of some other global variable? This solution may be good enough for me and you ... If we're not writing classes for distribution ... But they go against the grain of all the bennies I've read about classes. I'm not normally one to "cry 'BUG!'" ... But I think this qualifies.
