OS: Windows 7 - 64bit
When renaming a file in view "Thumbnails+Details" the renaming doesn't work. Intead, a message box "Folder conflict" is displayed.
Effect: Irritating behaviour. Functionality not available.
To reproduce:
1. In XnView Browser, switch to "Thumbnails+Details" view. (View » View as » Thumbnails+Details)
2. Select an image file
3. Press "F2" to rename it. Enter a new name an confirm.
Actual behaviour (bug): Message box "Folder conflict - The destination contains already a folder with same name, what do you want to do?" is displayed

Expected behaviour: no message box. File should be renamed.
