i even could not get the xpm import work.

i use redhat 5.1, siag-3.0.6-1.  After installing the siag, i did not set
any configuration ( should i ? ). i did try setting $SIAGHOME to
/usr/lib/siag, but the result was the same.


how did i do the importing ?  ---  run pw & -- use the plugin menu -
import - select the xpm file in the file selector -- then nothing happpen. 
i did the same for importing .pw file, it WORKED.

what is the problem ? would there be anyway to get some debug information
( say, through the syslogd) ?

any idea to find out the cause of failure ?
