Sometimes, when I try to open a .html file to edit it, I find that the page is in blank. However, when I go to the website, I can see that page perfectly well, without any problem. On some occasions, I only get part of the code of the file. It happens both with files that are already on the internet and files that I have downloaded to my computer. I don't get any error message or anything. At the bottom of the page it says "Line 1 of 0" and, curiously, when the file opens it is possible to undo, although nothing happens if I click on this option. Refreshing the page does not work and closing the programme and opening it again doesn't work, either. The encoding of these files is exactly the same as that of other files which do work (1252 - ANSI Latin I). I am using Windows 7 and the problem started when I upgraded from WinSCP 4.2.8 to 5.1.0, although it continues with 5.1.1.
