Double click action was my problem. THANKS!!!!!!!!!!!!!
Somehow I broke WinSCP. I wanted to set up an external editor to view .jpg files. Now, when I double-click on most any file it opens in wordpad or notepad. My Options->Preferences->Editors now only shows internal editor, but the problem still exists.
I want to use the internal editor and can't figure out how I broke the thing. Searching through the WinsSCP.ini file has not revealed any easy answers.
