Suggestion for a nice powerplane - clearance.

Set your relative coordinates to, say the bottom lefthand corner of your board.
Set a snap of 50 or 100 mils.
With reference to the bottom lefthand corner, highlight and copy the 
board-outline  - in your case this will probably be the lines on your 
Keepout Layer.
Enable all Powerplane layers and make one of them the active, the current 
layer - it will show you down the bottom of the screen.
Use the "paste primitive onto current layer - feature and paste your 
keepout-layer linework
onto the current layer, then make the other powerplane layer to be the 
current one and repeat the step.
You may want to do this for both the soldermask layers aswell.
Next, disable Highlighting and click on one of the lines.
A window pops up - asking which of the tracks you'd like to edit, select 
one of them - new dialog-box opens - enter your required track-width -
eg. 100mil - that results in a 50mil recess of the powerplane,  - do a 
global change and all trackwork for this current layer will change to 
desired trackwidth.
Do the same for all the other layers you've pasted the boardoutline down onto.
Hope this keeps you out of trouble.
