—, ah you'll need to download the free Construct Classic to open them (version R2 is in the General Discussion forum I believe). It's not too different in event styling though, so you might be able to port them over!
Hmm, pixel perfick a sub-event will only trigger if the main event does, and any objects picked will be carried on (eg: in a main event if you say "Object1 value hit = true" then it will only select all of the Object1 objects with a hit value in the first place).
One way to avoid picking any objects in the main event is by doing a System "Compare". Can you explain a little more about what you want to be done and I'll try making a cap file?
And no problem, happy to help <img src="smileys/smiley1.gif" border="0" align="middle" />
