I hear what you are saying and do agree with you. I can only post my own experience and tell you that AMX absolutely got involved and came to my assistance.
They have me as a customer for life.
My programmer is also completeley married to AMX. I guess I was just one of the lucky ones.
Having said that Im a firm believer in paying my vendors timeously and they in turn deliver.
What I dont understand is the programmers insecurity to have this out there. If they are good they are good and everyone's systems are so unique that (in my non expert opinion) that its hard to duplicate.
