I am trying to user LoadRunner to test some 3270 mainframe applications. I have been able to configure PowerTerm to get to the applications I want to test. But I have encountered two problems I need help with.

First, as I am recording my script, LoadRunner stops recognizing the keystrokes from the emulator. Does anyone know why this is occurring and how to fix?

Second, I have the ability to performance test with up to 100 Vusers. If I play the script immediately after recording it everything is fine (a single vuser). But if I set up a scenario in the controller to use the script, the vusers never leave the init status before I start getting errors. Does anyone have any ides here?
