[GRASS-user] Attribute table disappears

[david adam]

I had a simple attribute table working using the sqlite driver, and had 
successfully digitized a dozen or so areas in a couple of sessions.  Now 
the table has disappeared according to various tools.  I have only one 
layer in my map area.  when I try to add a table so I can rebuild my 
data, addtable complains that there is already a link to a table from 
layer 1, so I cannot start over.  Any suggestions for how to proceed 
(and how to avoid this in the future) would be appreciated.
Version is 6.4.2 under fedora 16 64-bit.
