Subject:   -33- 1.2 libpf Bug Hang on Exit, 5.2 VGX
Date: 8 Apr 1994 00:00:01 EST

  On VGXT running 5.2, calling pfExit when the phase is PFPHASE_LOCK or
  PFPHASE_FLOAT can leave an inactive window and DRAW process.
  Workaround: switch to PFPHASE_FLOAT or PFPHASE_FREE before exiting or
  kill -9 <pid> afterwards.
