I just updated to 5.1.5.2 on Windows 10.
When I password-protect (File->Properties->Security->Protect…) an .xls file and save it, then close Calc, but when I open it again, I am not asked for the password. When I go to File->Properties->Security->Protect again, the “Protect…” button is there (Not “Unprotect…”,) and when I click on it, there are no (obscured) passwords on the Password dialog that opens.
I also note that, when I click “OK” on the Password dialog, the “Record changes” checkbox on the Properties dialog always gets checked, even though I have NOT checked “Open file read-only” or “Record changes”. When I then un-check “Record changes” the “Unprotect…” button changes back to “Protect…”
I have successfully password-protected files with past versions of LO, and when I open them with 5.1.5.2, I am asked for the passwords.
What am I missing here?
Am I doing something wrong, or is this just broken?
