How to unfreeze a column that shouldn't be frozen

I have the following code that creates a grid:

var listGrid = new AW.Grid.Extended;
listGrid.setHeaderIndices([0,1]);
listGrid.setHeaderCount(2); //make room for filters
listGrid.setCellEditable = false;
listGrid.setCellText(listData); //data array
listGrid.setHeaderText(headerRow,0); //header array
listGrid.setHeaderTooltip(headerRow,0);
listGrid.setColumnCount(headerRow.length);
listGrid.setRowCount(listData.length);
listGrid.setId("listGrid");
listGrid.clearFixedModel(); //tried this, doesn't stop col-0 from being fixed
document.write(listGrid);

I don't ever tell column 0 (leftmost column) to be fixed/frozen, but it is (in both ie and ff), and I tried listGrid.clearFixedModel(); but that does not unfix it.

I need this not to be fixed. I don't even know why it is being fixed in the first place.

Yes, that should be much clear in the docs, I just remember answering the same question once, but could not locate it right now.
Just found one thread comented by Alex.

This did the trick:
listGrid.setFixedLeft(-1);

Thanks for the quick response!

I changed...
listGrid.clearFixedModel();
to
listGrid.setFixedLeft(-1);

and indeed it prevents anything from being fixed, but now there is what appears to be an extra column to the left of all the other columns.

(Also, now I see in the docs where it says that AW.Grid.Extended has a default-fixed column on the left, and so it makes sense why clearFixedModel() wouldn't make that go away (since that resets to the default, which is 1 fixed left)).

Any help with the extra-column would be appreciated. I can send screenshots of the problem (both on ff & ie) if needed.

Actually, just tried on a whim:

listGrid.setFixedLeft(0);

and that seems to do it, no fixed columns or extra blank ones.

I was under the misconception that setFixedLeft was referencing column-indices, when in fact it's just the number of columns to freeze. Sorry about that, thanks again for the response.
