After running ClearVolume, subsequent menu panels (eg, reslice, adjust contrast/brightness), open with transparent backgrounds. Here is a screenshot showing what I mean:
This happens on a Windows 7-64bit system, running Java 1.8.0_102 (latest java), It also happens with the java 8 that comes with Fiji (1.8.0_66). It does not happen on my macbook (OSX10.11) system.
Aside, I also found both WIndows and OSX that I could not export ClearVolume rendered volumes to Fiji, I could not get a console or control panel with "C", and could not get a display of the values selected by the sliders (like gamma, min, max, etc). Has anyone succeeded in getting these functionalities to work?
