--- Comment #7 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

still present.

It seems the app bundles with 'nngine.dll' component (COM server) which
provides some networking framework.
Among other stuff it contains an wininet/http communication wrapper which
operates highly multithreaded, apparently stressful to wininet.

Adding/removing debug channels seems to affect crash probability.
More/less trace -> changed timing -> thread race conditions (callbacks).

Use with following channels to check if hangs are actually result of exceptions
(thread holding lock died) or just outstanding requests (which take long/timout
at some point).

$ WINEDEBUG=+tid,+seh,+loaddll,+wininet wine ./toolbox.exe 

$ sha1sum Naviextras_Toolbox_Setup.exe

$ du -sh Naviextras_Toolbox_Setup.exe 
14M    Naviextras_Toolbox_Setup.exe

$ wine --version
wine-1.7.17-175-gc1bf61e
