Error when loading a dataset in xls format

[Francisco Javier Díez]

When I try to learn a BN from the an xls file (see the attached example), I select the file and click open, but the “Learn” but is still inactive, so I cannot learn the BN. If I select first a csv file, this button becomes active; then I can select the xls file and learn the BN.
