In other programs like notepad or firefox, when you type a folder name in the "File name" area and press the ENTER key, it opens that folder and shows the contents. In mIRC 7.41, this is different, it loads the folder as if its a script.
ALT+R -> File -> Load -> go to the top level of C:\ -> File name box, type: "windows" without the "", press the ENTER key.
It loads the folder as if its a script with the bottom of the script editor showing "File: C:\windows".
7.38 - opens the folder
7.41 - loads folder as if its a script
