Flash CS5 auto "merge" of two simple objects

Hey, I wonder how to disable the "auto combine" (or merge ?) of two simple draw objects (line, square etc.) on the same layer in Flash.

When i draw a 开发者_如何学Goline, and then a line that crosses it, they automatically merge in a cross. How to disable it ?

select your image, then go to modify--combine objects-- then click on union.

Okey, after some clicking I found a solution, you just click on Cap (you have drawn object selected, look in the right middle bottom screen) and select none. Have to learn some more about that ... thanks anyway.
