Spreadsheet stops working after creating a new sheet using a script and deleting exceeding col/rows
<p>Every time I create a new sheet using a script, my Spreadsheet stops working after a while and I have to kill the browser tab. </p>

<p>The problem happens after I correctly create the new sheet and I use the following two statements to delete the exceeding columns and rows. </p>

<pre><code>ss.deleteColumns(firstCol, colNb);
ss.deleteRows(firstRow, rowNb);
</code></pre>

<p>I have tried commenting the above and the Spreadsheet doesn't stop. </p>

<p>Do you have any idea, please?</p>

<p>Thanks, </p>
