Description:
1) open a CALC file with many columns (I have more than 200) and many lines (more than on the screen)
2) fix the 2 first lines
3) skip the lines down, until a few lines disapear from the screen and click in some case
4) insert a new column in the middle of the existing columns of the screen
--> the disapeared lines have gone back, and you are not anymore on the initial position you had before step 3

Steps to Reproduce:
1.open a calc file with many lines and columns
2.fix some first lines
3.skip down until few lines disappear, and click on a case just under the limit of the fixed lines
4. insert a new column among the existing ones

Actual Results:
the masked lines (the ones which have disappered in step 3) have come back on the screen, and if you click on a case of the first line under the fixed lines in order to write some value, it is not on your initial line but in the first not fixed line

Expected Results:
the only change on the screen is the apparition of a new column.
if you click on a case to put in a value, this is done in the right place
