Scissor tool splits both events on overlap

Hi everyone,

I tried searching the forums, but had no luck finding anything.

Here’s my problem: I recently reinstalled Cubase 5, updated to 5.5.3 and now whenever I use the Scissor tool on an event that is overlapping another one, it splits both of these events. Which setting do I need to change to prevent this? I just want the event on top to be split.
It’s a funny occurance as it didn’t do it before that.

Thanks in advance!
