The tag browser that appears in the left sidebar when you click the “…” doesn’t seem to do anything on my machine. Just me? Or a bug? The tag browser in the menu up top does work. I’m on a macbook using chrome in case that’s of any help.

@kirbyju I admit I did not know about the existence of the DICOM browser in the sidebar!

I investigate if this is specific to IDC deployment, will coordinate with OHIF developers.

I confirmed this is not specific to IDC OHIF, and submitted the issue upstream: [[Bug] Thumbnail DICOM Tag Viewer trigger has no effect · Issue #5502 · OHIF/Viewers · GitHub](https://github.com/OHIF/Viewers/issues/5502). You can monitor updates in that issue.
