When I type into Calc the text jumps up so it is half hidden and only the bottom can be seen. When I press enter or click in a new box it displays correctly If I save as a Microsoft document its ok

5.3.4.2 (x64) When I type into a box in Calc the text rises to the top of the box and only the bottom is visible. When I press enter or click another box the text displays correctly. If I save the spreadsheet as an excel file Microsoft’s product will display correctly and allow text to be entered correctly. I presume something has been upset by a recent update. (Probably by me)
Thanks for any suggestions
Tony
