  PCOMM v14 x64 crashed due to accessing an invalid memory address
  when the clipboard button is used.
  
  While downloading a file from the host using the PCOM VM/CMS
  session with the Clipboard option, PCOM terminated after a few
  seconds. This issue occurred because of an Array index out of
  bounds error.
  

Problem conclusion

• PCSXFER.DLL has been changed to initialize the Array memory
  address properly.
  

Temporary fix
