On a regular basis when I attempt to either move a file or rename it, it either freezes (in which case I have to shut the Directory down and reopen) or a screen comes up showing a choice between Windows or DOS with odd symbols (beneath the Screen). This was just an odd event, but it is happening several times in one day. Any advice? Thanks.
I'm not sure what that means. Do you have a screenshot?
If the process freezes, please generate some snapshots and send them to us:
Freezes while copying files often come down to something lower-level than Opus, e.g. the hardware itself, or drivers, or antivirus.
