[plt-scheme] text-input-port: editor has changed ..

Occasionally,  when  I  'Check Syntax from within  DrScheme v360.1  I 
get  this  error:

text-input-port: editor has changed since port was opened: 
#<struct:object:...s/test-suite/tool.ss:105:8>

It seems to be benign, except  that  I  have to  run the definitions to 
get syntax errors reported.  Sometimes, after running a few times it 
will stop reporting the error and sometimes not.  I haven't noticed any 
pattern, and certainly no particular source file that it occurs on more 
than  others, so I really can't supply you with a reliable test case.

I'm just wondering if anyone else has seen this error under the same 
circumstances?

Thanks,
