I am using the Nitro demo in Fl Studio

In Nitro,

I click on "CFG" mode ( top left in the GUI ), I click on "Predef" ( that appears in the GUI ), but then I can't seem to be able to click on one of the graphs to select it.. can you confirm this?

I can switch between the pages of graphs but can't select one. I have to click "exit" and then the graph is the same as it first was.. weird..

Is it because it's a demo, or is it a bug? Can someone check it out for me? perhaps a demo user? and someone that has purchased it? preferably in Fl Studio but any host will do..

I received confirmation from PSP that it is indeed a demo limitation
