I have encountered some difficulties using Erik More xml data sorting class (file in macxml.zip in file area):

1. Sorting table by double clicking in column header will not underline this header.
Sorting is invisible. Is it possible to add underlining or some other visual property to output so that user can see by which column table is sorted?

2. For long table, sorting takes some time. However, mouse cursor will not change to hourglass.
Is it possible to change mouse cursor to hourglass when sorting is in progress ?

3. Where to find more examples about sorting xml data in client side and for document entry: adding many rows having one document header.

Rick's questbook and ComCodebook attoreny examples will not demonstrate document entry. I need to edit invoices in client side.

In file area there is another example, xml_export . But this class has same problems.
