Seeing <------> instead of tabs - how to disable ?

["Ian Brown" <ianbrn gmail com>]

Hello,

I had installed mc on FC9.(mc-4.6.2-3.pre1.fc9.x86_64).

When I open a file which has tabs inside, I see :
<------><------><------> instead of the tabs.

I did not have such a thing with Midnight Commander on earlier versions
of mc.

How I can replace these <------> with spaces ?

Regards,
Ian
