Several times lately when I try to open a Calc file I get a warning; File is corrupted and cannot be opened. Then Calc offers to try to recover the file but warns that the data shouldn't be trusted.
At least once I let Calc recover it. All the data seemed fine.
Today I just closed out all the warnings and the file opened fine the next time I tried it.
What's happening here?
