split tool is not good

hello steinberg,
now i have one track , and rec…one bar to 4 bar, ane then again .
so on the track, there are two events, now i use split tool , i just want to cut the newer event, but the first event is cutting at the same time, how can i do.

ps i bought the nuendo 5, in the nuendo 5 , i can only cut the newer event, so i can more easily to remove the under enevt(s) .
