Topic on Project:Support desk

I was away from Wikipedia for some time and in the interim there seems to be a change in the Preferences:Editing that eliminated the option to set the number of lines displayed. The edit window is now sizeable on the fly; however, it's frustrating to set the window to the size I want and have that revert to the default size every time I use the Preview command. How do I set the window to be 19 lines exactly?

So simple; I never would have known where to look for it, though. Thanks for the assistance!
