Using Ubuntu-Mate 18.04 to access files on a Western Digital MyCloud. NAS is mounted at startup using an fstab entry. Most of the time it works just like another local drive. But occasionally when using caja to move/copy files from the NAS, caja just stops. The dialog box stops updating and none of the buttons on it work. I can close the dialog box but caja is still stopped. Trying to move/copy another file brings back the dialog box with the stopped progress bar and adds another progress bar for the new operation waiting for the old one to complete. The only way I can clear this is to kill caja or restart the computer. This usually happens with a small file (<1k). It also seems to occur only copying/moving files from the NAS. It never happens going in the other direction.
I initially thought it might be a problem with the NAS but I can open the file with pluma and save it locally with no problems.
Does anyone have a similar setup or seen the same problem? Any suggestions appreciated. Thanks.
