Bug report

[RobertPJenkins]

During testing, was initially working but now receiving console error when running preview:
org.scijava.thread.DefaultThreadService.getThreadContext(DefaultThreadService.java:155)

Seems to fail when trying to run preview for a second time on same image. Thought it might be because I had files from the folders it was trying to delete open, but it isn't.

Further error output. Seems temperamental if runs again after initial preview.
