After install EmEditor v19.9 beta 2 (19.8.92), no file open direct by double click. The EmEditor came to front and open a new Untitled-xx.txt
From commandline without parameter (“EmEditor.exe” “filename”) it is the same. Also from emedtray.exe with “new and past” it doesn’t work. I tested with “EmEditor.exe” / “filename” and it works. It works with parameter and also with only an slash.
