GUI apps on windows do not startup anymore

[Riccardo Mottola]

Hi,

I updated my core installation on windows. Now no application seems to 
start up anymore. I use win32-winlib

If I try to start e.g. Ink, it will churn for a bit and drop to shell 
prompt again, without any window appearing. IN the event viewer I only 
see these entries:

It is interesting that they are double. Any clue what could be 
happening? i have never seen such errors.
