**Hi All** , I have to ask about Senocular “_ **Getting Started with ActionScript 3.0 in Adobe Flash CS3** _” great tutorial, here link to tutorial: [http://www.senocular.com/flash/tutorials/as3withflashcs3/?page=1](http://www.senocular.com/flash/tutorials/as3withflashcs3/?page=1) , and to download samples: [http://www.senocular.com/flash/tutorials/as3withflashcs3/AS3WithFlashCS3.zip](http://www.senocular.com/flash/tutorials/as3withflashcs3/AS3WithFlashCS3.zip)

**DrawingBoardApplication.fla** , and **DrawingAPICheckerBoard.fla** from tutorial samples, after compiling it will be turn my processor into big power-hungry (about40-90% processor usage).

Setting **mouseEnabled** or **mouseChildren** property to false give nothing here. If You move mouse around screen, even blank screen, processor usage will increase. Why?

I need turn this nonsense mouse usage off. This problem is very important for me because I’m developing some apps with many elements, naturally all in AS3 classes.

Can everyone help me? The samples are only samples from tutorial, so is easy for all understand, what i mind. Thanks, and apologize for my english 🅱, I’m firstimer here=)
