    So the ROI widget is showing up completely blank in the display? This sounds like it could be a graphics issue. What version of ENVI are you running? You can find out by going to Help->About ENVI to see the version. The latest version is 5.3.2. Also, what operating system are you running ENVI on - windows, mac, linux? One thing you might try is to launch ENVI+IDL. In IDL, go to Window->Preferences->IDL->Graphics and change the rendering method from hardware to software. Save this setting and relaunch ENVI. Bring up an image in a display and then launch the ROI tool. Do you see the dialog?

    Hello, I am using 5.3.1 on a Mac. I tried your IDL workaround but it did not work. Thank you.

    Are you able to display images and the ROI tool in ENVI (not Classic)? How are you launching the ROI tool in Classic? Can you post a screen shot of what you see in your display?

    Have you tried resizing the ROI dialog? I noticed that on Mac it sometimes comes up blank but if I resize it (make it longer horizontally) the table widget shows up.
