Unable to Save Safari Bookmark
I'm running Yosemite 10.10.3 on a MacBook Pro 13.
When I go to save a bookmark in Safari, instead of the window as shown below, the window will extend past the edges of the screen width wise, making it unable to save a bookmark. I've asked for help on this a couple of times, and the answer has been that the bookmark file is somehow corrupt, and have deleted it, but this keeps recurring.
Any ideas on what the problem is and how I permanently resolve this?
Mac Pro, OS X Mavericks (10.9.3)
