In LabWindows/CVI, using the project menu, instrument (.fp) drivers are loaded using the Options/Library Options... Menu. Project A uses these drivers. I need to load project B that uses different instruments (some instruments for project B have the same name as the instruments for project A, but have different functions). The problem I see is that if the instrument driver list is changed for project B, the list of libraries for project A is no longer correct (the instruments for project B are loaded when LabWIndows/CVI is launched). Is there a way to have project A have one set of instrument drivers and project B have another set?
