Under certain conditions, which I have not yet been able to pinpoint, the
python gui hangs forever when right clicking on vector map to list the
attribute table. Change the gui to tcltk and the problem disappears, the
attributes for the same map are listed correctly.
I am using WINGRASS 6.4.0 standalone, stable release, under Win 7 Pro. and
Python 2.6.4
I will persevere to try and pinpoint the problem a bit better, but I would
really like to know if anybody else has had a similar experience. Ownership
and permissions of all the files involved appear to be ok, although one
never knows for sure with Win 7!
thanks

At least in GRASS 7, this seems to happen when a vector-database connection has not been defined, has been defined incorrectly, or the vector does not have an associated attribute table. Under those conditions, there is nothing for the table manager to display. The problem seems to be in the error trapping somewhere.

Thanks Michael but I don't think this is the problem in my case, I am using
the default DBF database, no DB connections required. Also remember that it
all works well when I use TclTk as the GUI, and all works well when the
number of DBF files in the mapset is less than approx 188. I haven't been
able to find any other cause so far, but it could be Python related rather
than GRASS, when I kill the GUI that hangs I get an error message to the
effect that Python.exe is not responding. But why should the number of DBF
files be relevant???
