Ftp will not replace existing file, changes name to temp

I upgraded to 9.86d and can think of nothing else that I have changed.
Below is typical from the list of tasks on the FTP program
Thanks for your help in advance.

PORT 192,168,2,3,11,92
200 PORT command successful.
STOR gizmo.giftemp
150 Opening BINARY mode data connection for gizmo.giftemp.
226 Transfer complete.
RNFR gizmo.giftemp
350 File exists, ready for destination name
RNTO gizmo.gif
550 gizmo.gif: Cannot create a file when that file already exists.

I am replying to my earlier message. I went back to version 9.84d replacing the upgraded version. Everything works okay now. That suggests that there is a bug in 9.86d.

Again the problem is new uploads of files to my weather web site cannot replace the existing files. The new file names are changed to the regular name with the extention temp added, like this. . . gizmo.giftemp.

Brian - I read about the new renaming routine that Wdisplay has. I guess my problem is that the temp files are not renamed and my web site does not show the updated files as the old ones remained in place. Regressing back to a prior version, fixed it because that was before your new renaming routine was implemented.

Brian - I reinstalled 9.86d and went to the setup ftp menu, I checked the rename file on server box, saved and exited the program. Then I called up the program and unchecked the box under the same menu and exited the program. Finally, I called up the program and all is well. Hope this helps.
