I am not sure this is a known bug and it sounds very annoying.
Can you give me:
- the VM exact version: Evaluate "Smalltalk vm version"
- the image exact version: Evaluate "Smalltalk systemInformationString "
Does it crash at start-up reliably, I mean at every start-up ? Does your application adds extra behavior at image start-up or image shutdown ?
If it crashes reliably can you put it to download from somewhere like a dropbox, google document or one drive and share the link with us ? Else send it to me I'll do that.
