both versions work on my pc, but on the pc where i have bloomberg 
installed the things i described do not work. the rcom peckage works, 
but comCreateObject creates an object which is somehow different from 
what COMCreate creates. especially the Slot "ref":  row is not present 
anymore and so RBloomberg package functions do not work.

any idea?
