@paul.moore  all scripts failed.  it's like pyw.exe does not run at all (or quits shortly after.  i have about 5 proprietary scripts.

going back to 3.7.4 everything works as before.   I do suspect there is something wrong with the way that 3.7.5 was compiled for pythonW.exe


 python/pw.exe works fine for both 3.7.4 and 3.7.5 (x86 and x64 versions)
pythonW/pyW.exe works fine for 3.7.4 but not 3.7.5 (x86 and x64 versions)

This is the first time i've ever had this issue.  python 3.6.x.

I originally thought it was a win10 issue because I am setting up a new computer and using 3.7.5 for the first time.  (other computer had 3.7.4).

I will ask my programmer to give some sample code.  But really any existing script you have should work for testing 3.7.5 pythonw.exe , particularly if it requires a couple of non-core modules to run.

Let me know if you are unable to reproduce it.
