This is one of the rbbr's restrictions.
Both of "Load Script" and "require library" have this kind of problems.

This is also a restriction.  
But in this case, it's a bug. isn't it?

If "reading libraries process" is separated from main rbbr process,
It may be solved. But I don't think to make rbbr complex.
Because rbbr is a sample application of Ruby/GTK2.
