We’re using the SNAP 2.0 beta version on a Windows machine, and trying to display RGB colour composite images for Landsat data with the menu option Window > Open RGB Image Window. For Landsat 7 and MSS data I get the expected dialog box and then the RGB composite opens. For Landsat 5 I get a brief indication something is happening, the cursor changes, the first time I attempt it but the dialogue box doesn’t open. On subsequent attempts nothing happens.
I installed the software this morning, to double check my colleagues findings, so just have a small log file in that directory that I’ve just emailed you.
