About the first problem: Toolbar sticking in Main Monotor. It comes from a user request to limit toolbar in screen. So we add the boundary. But unfortunately we did not consider the multi-monitor situation as you meet. We'll try to fix it.
??And maybe we need some help from you to correc and verify it for we do not have multi-monitors.
In our implementation, we limit the toolbars in a Rectangle(0, 0, Screen.Width, Screen.Height). It means in main monitor, not for multi-monitor. I think it should be change to (0, 0, Screen.DesktopWidth, Screen.DesktopHeight). We'll modifiy our code as this and build a nightly version later. Please help us to verify it once it comes out?
About 2nd problem: Prefix saving. Could you help to check the file:"C:\Program Files\CnPack\CnWizards\User\Prefix.ini" (or in your customized installation directory of CnWizards) after you press OK button in prefix settings dialog?
I think it should be saved and changed after presing OK, not until IDE exits. If it does not changed, it should be a bug here.
