    54 Comment (by Tom Goddard):
    55 
    56  Thanks!  That makes more sense in terms of what I see in the crash stack
    57  trace.  And when I try dragging the sequence viewer window out of the main
    58  ChimeraX window I was sometimes able to get it to crash with the same
    59  report as you sent.  This is a Qt bug.  When I tried with the ChimeraX
    60  daily build which uses a newer Qt version (6.10 instead of 6.9) it never
    61  crashed dragging the sequence viewer.  This bug probably effects dragging
    62  any window out of ChimeraX not just sequence viewer.  If you are seeing
    63  this crash more than once you might want to use the ChimeraX daily build.
    64  Thanks for helping figure out what causes this crash!
