Apply patch to Interpreter.cpp (Program Bug and Problems)
now I've found out what caused the issues reported in
Interpreter.cpp line 192:
OP_POLY was treated as OPTYPE_NONE, but it should have been OPTYPE_INT.
The result was that the label replacer got out of synch with the byteCode.
I can't check this into the svn, as I'm not a kidbasic dev so someone of them would have to apply that patch.
