Ah.... thanks for that. That seems to have done the trick. But I'm not sure
whether I have copied the right jvm.dll file into the path.

I have 3 places where a jvm.dll file can be found: 

~\Java\jre1.6.0_01\bin\client   -    this is the one i copied

Did I copy the right one? or do the all have exactly the same file but just
placed in different directories?

Many thanks
