Thanks! I'll take a look at that, but I'm not able to change what runs at
system startup.
It is a bit weird that multiple users (from different organizations)
started to experience this after a Cygwin update. If I'm using an older
version I don't have these issues on the same machine (the cygserver
service does not run at system startup). Is there any change between 3.1.7
and 3.4.2 (the oldest version I was able to use in my tests) that could
have caused it?
