Rotate Object for a Merged Chunk?

[bruce simonson]

Greetings,

I have two chunks of imagery for a glacier terminus, which I have successfully merged into a single chunk. 

However, it appears that I cannot use the Rotate Object tool (from the tool bar) to set the x, y, and z axes for this merged chunk -- specifically, the "rotate object" icon in the tool bar is greyed out.

I would like to set the model axes for the merged chunk using the workflow described in this post:

What am I missing?  Is there a different workflow for rotating the model axes for a merged chunk?

Cheers,
-Bruce

PS:  I'm using standard edition 1.2.6 (build 2384) for this project; I have used professional in the past, but don't have access to professional at the moment.

Right click on the merged chunk and select 'reset transform', then you should be able to rotate the model.
