Hi, For a long time I was unable to use the nifty zoom feature in the Hobbit/XYMon graphs. The problem is that dragging the mouse invokes the browser image drag-and-drop functionality, preventing the zoom.js machinery to do its work. (So this is a different problem from what I read about in several threads, with people getting a blue box instead of a working zoom image). Today I finally decided to look into the problem, and found a fix. I though I would post it, in case it should be helpful to others. Basically, it's this one-line patch: --- /etc/hobbit/web/zoom.js 2010/04/07 08:03:39 1.1 +++ /etc/hobbit/web/zoom.js 2010/04/07 08:06:10 @@ -550,6 +550,7 @@ gMouseObj.dragging = true; gMouseObj.saveCurrentToStartPosition(); gZoomGraphObj.drawSelection(gMouseObj.currentX, gMouseObj.currentY, gMouseObj.currentX, gMouseObj.currentY); + if (e.preventDefault) e.preventDefault(); } else if (gMouseObj.rightButtonPressed()) { var test = true; } I'm using hobbit 4.2.0 (and Firefox 3.0.18), so this is old stuff ... my apologies if this is already fixed in a newer version. Hope this helps, - Kristian
