hi, i a new to wxRuby, but have been able to create a frame/listcontrol  
and  
fill the list with items.  
What I do not understand is why the vertical scroll bar on the list does  
not  
respond?  
I have 15 items showing and 50 in the list. Do I need some event to  
activatte it?

It is hard for us to diagnose the problem, without a minimal sample of  
code,  
to go by. If you could, please create a minimal sample that replicates  
the  
problem, and send the code in your email to the list, and we will be  
able to  
figure out what is going on. Try not to post the original code, as it  
tends  
to have other stuff in there, that we don’t need to replicate the  
problem.

Thanks,

Mario
