Error when writing results: File "Tkinter.pyc", line 1378, in event_generate about namebench HOT 6 CLOSED

I'm not sure what to make of this error. Can you see if the newly uploaded 
1.0.2 version 
has the same issue?

I am also getting this with 1.0.2.  Same error as the OP.

expected boolean value but got "??"
  File "libnamebench\base_ui.pyc", line 46, in UpdateStatus
  File "libnamebench\tk.pyc", line 81, in msg
  File "libnamebench\tk.pyc", line 49, in AddMsg
  File "Tkinter.pyc", line 1378, in event_generate

I am also 64-bit on Win2k8.

Not sure if it helps, but here is the more complete stack track from the log 
file:

Traceback (most recent call last):
  File "libnamebench\tk.pyc", line 86, in run
  File "libnamebench\base_ui.pyc", line 73, in PrepareBenchmark

  File "Tkinter.pyc", line 1378, in event_generate
TclError: expected boolean value but got "??"

Clicking "Start Benchmark" a second time allowed it to complete with no errors. 
Entering new DNS servers and clicking "Start Benchmark" a third time eventually
failed with another error:

A fourth run with the same DNS servers from attempt #3 completed successfully 
with no
errors.

I was not able to replicate this on Windows 7 64-bit Home Premium, but I did 
put in 
a hacky bandaid for this error. Can someone who experienced this issue try this 
debug build of namebench:

http://namebench.googlecode.com/files/namebench-1.0.2-test-issue-47.exe

It patches my code so that if event_generate() fails for whatever reason, it 
simply 
ignores the status update and catches it on the next cycle. This appears to be 
a 
thread-safety issue with the Tk libraries, so I'm just masking it for now. I 
have a 
feeling this is not the only place I will be seeing this issue.

While there may be other thread safety issues with Tk, I believe this one has 
been fixed 
by version 1.0.3. Please let me know if this is not the case.
