No, the last loaded one will be displayed and then updated. The previous ones 
are forgotten. This is true for each part instance, but you can have multiple 
instances as what is done in kgraphviewer when showin tabs.
.... In fact, I just checked the code and it is buggy: the watched files are 
never removed even if the only one watched is the last one. I have to correct 
that.

This is configurable, the KMessageBox::questionYesNo uses the 
"reloadOnChangeMode" string as its dontAskAgainName parameter. So, you should 
be able to set the correct value in the configuration file.
