I cannot reproduce this issue because I don’t have Total Commander. Is there any other ways to reproduce this issue using Command Prompt or Explorer?
Yes, I can reproduce it from Explorer too. I right-click on a ZIP file, select EmEditor from the context menu and wait. It seems that nothing happens, but when I Alt+Tab to EmEditor I see its “Select Encoding” dialog.
I cannot reproduce this issue using Explorer > select EmEditor a zip file. I tested both on Windows Vista and Windows XP.
