Thanks a lot - it works fine :)

I've made this class which works perfectly

class Consolefile:
     def __init__(self):
         self.file=None
         self.status='init'
     def start(self):
         self.filename="%s\\%s_console.log"%(cfg.logdir,FILEID)
         print self.filename
         self.oldstderr=sys.stderr
         self.oldstdout=sys.stdout
         self.file=open(self.filename,'w')
         print >> self.file, '#Logging STDERR and STDOUT to this file'
         sys.stderr=self.file
         sys.stdout=self.file
         self.status='started'
     def stop(self):
         print >> self.file, '#Console logging stopped'
         sys.stderr=self.oldstderr
         sys.stdout=self.oldstdout
         self.file.close()
         self.status='stopped'
