Some tiny settings difference in Eclipse I bet. Maybe a "+" is open on 1 machine and not the other.
* - Package Win32::OLE::Tie Implements properties as tied hash
Object methods and properties
The object returned by the new() method can be used to invoke methods
+or retrieve properties in the same fashion as described in the docume
+ntation for the particular OLE class (eg. Microsoft Excel documentati
+on describes the object hierarchy along with the properties and metho
+ds exposed for OLE access).
Optional parameters on method calls can be omitted by using undef as a
+ placeholder. A better way is to use named arguments, as the order of
+ optional parameters may change in later versions of the OLE server a
+pplication. Named parameters can be specified in a reference to a has
+h as the last parameter to a method call.
Properties can be retrieved or set using hash syntax, while methods ca
+n be invoked with the usual perl method call syntax. The keys and eac
+h functions can be used to enumerate an object's properties. Beware t
+hat a property is not always writable or even readable (sometimes rai
+sing exceptions when read while being undefined).
If a method or property returns an embedded OLE object, method and pro
+perty access can be chained as shown in the examples below.
Your answer is in the quote above. More specifically, a little bit of googling leads to this http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel._application.activechart
. I dont know what "Nothing" translates to in Win32::OLE.
