Why difficult ?
I started to reading the first part of the lessons and seeing the video several times.
Then starting the subject.
Starting with Enhance/Adjust lighting.
Jumped then in CM3. My curves where on the other monitor.
the strange thing began with the mask k.
When i where in the wgCMYK mode and the K line where made a fade then moving the fade downwards made the dragon black.
But the stragest thing happended when jumping to Lab mode.
The points where vanished.
So i did the same with the K in lab mode. But the effect s where strange.
So what did i  wrong. ? Seeing again the movie. No i did not wrong.
So at last i thauhgt , i make a Snagit movie from this fenomena , for Mike.
I did the whole sequence again. But on that moment it goes right. No problems.
I did it not on a other way.
My opnion is, that sequence of handling is not stable enough.
There is something wrong.  It could also be my computer, with my prgrs on it. Who nows.
Has nobody experienced problems with it , or be I the only one.

some quick checks Fritz...

Is the GCR setting correct for the mask? 

Did the end points of the K curve slip inside of the frame more than a little bit??
the only thing you do with the K mask is use it as a fader. 

Did you pick a good neutral??

Did you set a neutral or a highlight? 
I know this may sound "off" but i just want to be sure you have everything going right....

OK Fritz,
I looked at the Vid....

It looks to me like you are faster than the screen refresh. 
Try making smaller adjustments on the K channel and giving it a second or two to update. 
When you slowed down near the end the screen seemed to catch up...

Let me know if this works. 

It was working as the video progressed.

indeed it was working.
but before i had several times that in the wgCMYK mode, fading the k  channel gave a black picture.
After going to the lab mode, the two points dissapeared.
So i did  the same with the K channel  and the fade did not work well.
I now now, it will and can work.
But i had doubt before.
I am busy now with the nice garden and see about the same problems.

I have some problems with it also. It varies in which direction I am moving the flat mask curve line (up or down) and its not consistant. It may have to do with the refresh rate. If I start at the top and work down slowly it sort of gradually fades until I get to one point then it changes drastically in one step. If I work my way up nothing happens until I get past half way. Then it jumps into the "mars" colors. It ends up not being a gradual change. Sometimes nothing happens on the way up so I wait thinking that the computer is locked up. Eventually it changes. I'm running a Pentium 4 with 2g ram. I have most everything shutoff in start up (except Spyware etc)
Thanks Joe S

well this is where Der Curvemeister needs to look into the action in the programming I think.

I'll try this again and see if I get similar results...I had not noticed it before.

To use the K mask as a slider, select K as the mask, and do the slider trick with the mask (not the K channel of wgCMYK - that may be what is creating a black picture. 

I don't have an answer for the "sudden jump" problem that both Joe and Frits are describing.  I'm using a fairly slow (1.7 GHz) system, and the "K slider trick" works OK for me.

One thing I have noticed is the keeping the mouse in the right (light colored) margin during the drag operation works more consistently - sometimes the curve does not react the the movement if the mouse is in the curve window itself.  Maybe this is the problem Joe is seeing - if so, try dragging in the white margin of the mask.

BTW - it just occurred to me that the mask you choose is immaterial.  The important thing is that the line be horizontal.
