RfcCurrentClient and several guixt.ini files: We have a local guixt.ini file in which we use "SwitchTo" for a second guixt.ini. In this guixt.ini we use "RfcCurrentClient Yes" and another "SwitchTo" leading to the final guixt.ini, which does not contain an RfcCurrentClient statement. Will GuiXT then use "RfcCurrentClient Yes" or the default "RfcCurrentClient No"?

GuiXT uses "RfcCurrentClient Yes" in this case. A "SwitchTo" command doesn't remove the configaration parameters that you have already set.
