The problem is not "tab", but the "scrip"t I used (for "tracer") and owned "Mach3FR". Having spent over 100 hours to make this "screenset", I did not want to spend another hours for change the causes of the problem. I'm on version 2.0 for my personal use with further option.
"I take it this is a flash based screen set?"
- No, only images created with photoshop
ps: Sorry for my bad english
