So, I have been working on some code all morning, saving as I went, and I left my desk for a lunch break. No transactions were open, I have no encryption ANYWHERE in the domain, noone used my PC and when I get back I have this: ![alt text] : /upfiles/Scrambled_SSMS.png Similar effect on all tabs. I have closed and opened tabs and they stay the same. I have copied text out of the editor into Notepad and it pastes in plain text. Pasting this back in though, and it goes all scrambled again. Does anyone have any ideas what has happened to me and how I can get out of this situation please?
