XYplorer Beta Club

Hi,
For some reason I can no longer move files with simple drag and drop using xyplorer. It is most frustrating. I have gone down through all the posts and checked the help file, but I cannot come up with a simple solution. One minute it was working and after six hours of playing around I cannot find a solution.
I use Win 10 and latest XYplorer.
Thanks

You did restart your computer?

Apart from that, are you using XY's custom copy?
If that's the case, do you have / had a process running named "XYcopy.exe" after a copy operation was already done?

Thanks for coming back to me. I did re-boot. Xcopy was not ticked. I decided to re-install the software and that worked a treat. I don't know what happened. I would prefer to have known, but the frustration and need to work called for drastic measures. Thanks for your assistance.

Maybe you had ticked this:
Configuration | Menus, Mouse, Safety | Safety Belts | Disallow left-dragging from tree and list
