Using version 8.40.0117, I have this bug to report.
Repro steps:
1) Go to any folder
2) Create a folder named "temp" (or anything)
3) Hit Ctrl+N to create another new folder - OR - rename an existing folder
4) Write "temp" as the folder name (same as in step 2) and press enter
5) A "Confirm Folder Replace" dialog comes up - click the No button
Result: An endless loop of "Confirm Folder Replace" dialog continue to come up when you click No, and the only way to get out of it is to either click the Yes button or move the mouse cursor to the new folder name and put in an extra character so that it doesn't clash with the existing folder.
The way Windows Explorer handles it is that if you click No, it renames the new folder you're trying to create to the default "New Folder".
