Insert issue 1: Insert a new row. Enter in values. Click commit and the new row moves to the top. If it is a large data set, it can look like the new row disappears.
Insert issue 2: Insert a new row. Copy a cell value from a different row and paste it on the new row. Click commit and the cell is blank. If the value is copied before creating a new row, the cell value is retained after commit.
WORKAROUND:
In the case of Issue 2, copy value first, before creating a new row.
STATUS:
Waiting for fix in a future version of SQL Navigator.
