Windows: Export Spliced Image fails with data loaded

[sorghumking]

Steps:
Load data for a site with imagery (right-click site node, choose Load).
Return to Data Manager by clicking Go to Data Manager button in lower-left of main window.
In Data Manager, right-click site's image node, choose Export spliced image, select a splice and export, get the error messages below.

This does not happen if data isn't loaded. First guess was running out of memory, but according to Task Manager, Correlator is using about 1.8GB of RAM (on a machine with 32GB) with all 342-U1410 imagery loaded. Related to loading the same image twice? Holding onto a file handle from initial load?
