These are some of the things that are not functioning correctly for me in KSpread:
1) When I go back later to use the same file as I saved earlier it is gone/it wants to give me an older recovered version.
2) This document (which was originally developed by me in Excel), does not let me change the formatting of the cells that were original to the Excel version. For example, I try to tell it to change the font size from 12 to 10, and it does nothing at all. It doesn't seem like the translation into the ODS format was anything close to complete. It ought to be forgetting that these cells used to be Excel ones.
3) The now() function is only displaying the date and not the time on my document. I think I fixed that once my totally reprogramming the sheet, but unfortunately that version has now disappeared. I had to really fight to get it to give me the AM and PM at the end, too.) For some reason there is one cell that is actually displaying correctly at the moment. But none of the others are letting me change their formatting to show both the date and the time. I have also tried using the currentdateandtime() function, it also has the same issues.
