Hi Dalvi,

Another thought... the "Personalize columns" form will be populating the available columns using an AJAX call.

When the form is loading, inspect the Network traffic of the web browser to find the xmlhttp.do calls being made to retrieve the data.

I wonder if the columns for the table are being returned in XML format, but one of the columns contains an invalid character that returns an error in the AJAX call.

If the issue was not seen before your new column was added, check the definition of the new column in sys_dictionary and ensure the Column Label and Column Name do not contain "funky" characters.
