Hugs does not free file handles on stop pressed

Hi, If you abort a Hugs computation which has an open file handle, it remains open. I.e. do a writeFile "filename.txt" (show (1, last [1..])), press Stop or Ctrl+C and the file handle remains open. However, doing "print 1", or just about anything as the next operation, results in the file handle being closed after that command aborts. I suspect that this means there is some routine out there that closes the file handles and does the tidy up - if it could be invoked on abort that would be handy. Thanks Neil
