Running Windows 10 Paradox 9 sp3

Right Click copying a large file will crash Paradox. The Copy is always 
completed and the message bar says that it has been completed. However 
running Paradox in Windows XP Service Pack 2 compatibility mode works 
fine except that when closing Paradox it then causes a Windows 10 exit 
error. Also using the Paradox Utilities ---> Copy Function dialog works 
fine in Windows 10 normal mode.

Copying in code in Windows 10 works fine. So copy("File1", "File2") or 
filesystem Copy.

Can anyone shed any light on what to tweek to get rid of this little bit 
of annoying Windows 10 nuisance.

Thanks
