I have just installed the new version. Tables appear to work better now compared to 5.20.0. However if I select two adjacent cells in a table and then call CombineCells it works but the whole page flashes black and white. It lokks like the cursor filles the page. It stops when I click on the screen.
There was also a problem compiling in wprtepaint.pas. NumOffs is not defined.
