I don't have an answer on your issue but thought I would add a comment on the Sprutcam builds.
Lately I have noticed that the SC website is listing what I would call daily builds and not actual released versions. These use to be available on a FTP site which were mainly bug fixes to specific problems. You would report a problem and usually several days later they would email and tell you a patched version was available for download.
After reading several internet postings I believe people are under the impression these version are released versions rather than daily untested (or limited tested) builds. Being a software developer the company I work for does a similar thing. Each night all of the checked in source files are re-compiled and a new version is created. In our case these are for internal testing and not general public release. I am pretty sure this is what you are seeing on the SC site. If this is what they are doing I can see many frustrated uses if they don't understand what is really going on.
My frustration with SC at times has been what you are experiencing. In one version a feature works great and a couple versions later it's broke. At times it feels like we the customers are the real test engineers, but without the knowledge of what specifically was to have changed or been fixed.
At work we call this 'Living on the Edge'.... At times it's ok, but not when you are trying to use the software to do a real job.
