Dear René,Thank you for response. I did not make dist-upgrade (except apt-get update && apt-get upgrade) because everything had been working fine and one day I discovered that values in cells were not calculated but concatenated. Believe me, I was surprised.
Two snapshots as an example are attached.
Now, after dist-upgrade Calc works fine. Best regards, Dariusz Lomot
