My page is 930 wide and 600 high.
I'm trying to create a horizontal guideline at 300 and a vertical at 465.
This seems to be a hassle.
I get the vertical to 465, and then go to place the horizontal guideline, but it keeps snapping to the guide origins together. So I attempt to move the guide origin on the vertical to 300, but trying to move this up and down also moves the guide line itself all over the place.
How do I enter in specific coordinates for the guidelines to go to?

Hi

Double click the guideline to bring up the coordinates dialog.

You can disable snapping by clicking the top button on the control bar (it's a vertical bar on the far right side of the window, if you're using default placement).
