The editor used was IE7.
I created a table with the Table Wizard. I clicked on the "Columns: +" button twice to expand the table to 4 columns and then clicked on the "Rows: +" button twice to expand the table to 4 rows. I then selected the cell at position 1,1 and clicked on the "Column Span: +" column twice to cause the cell to span columns 1,2 and 3 in the table. I then clicked the "Row Span: +" button once and instead of having this cell span rows 1 and 2, two columns were inserted to the left of the cell and the cell at position 4,4 was changed to span two rows and 3 columns. The original cell still only spanned a single row.
I've reproduced this exact behavior multiple times, but found no mention of anything like this in the forums. Does anyone know what might be happening here?
Thanks,
Mark
