After update to 4.01.0036: exe fails to initialize graphics window

[Huib]

Today I updated Vizard from the previous version to 4.01.0036

Our projects run fine with winviz.exe, but when I build an exe, I get this error when I try to run it:

Traceback (most recent call last):

(...)

File "C:\Program Files (x86)\WorldViz\Vizard4\python\viz.py", line 2240, in go

RuntimeError: Failed to initialize graphics window
