horizontal scroll?

In the script below, whan the find function finds a string at the end of a line it scrolls some of the text off the screen to the left. It does better if I change the 2 to 1.1 in the scroll-to function, but it still scrolls a couple of characters AND it puts the highlighted string at the bottom of the page instead of the middle. How can I make this stop? I need to scroll all the way to the left before showing the text. I simplified the find routine from the one found in editor.r. The same problem exists in that editor. Any ideas?

I changed the scroll-to function to scroll-to: func [txt /local xy] [ xy: (caret-to-offset text-file txt) - text-file/para/scroll text-file/para/scroll: min 0x0 text-file/size / 1.05 - xy my-slider/data: (second xy) / max 1 second size-text text-file ] 1.05 instead of 2 eliminates the horizontal scrolling, but it puts the found text on the bottom line of the display instead of in the center. If there's a simple way of scrolling the text up 2 or 3 lines, I'd like to know it. I'm still experimenting, so I may find the answer. Jim
