Checked against an older version I have, and the older one does bloom and glare, but the new (contained in the Mar 29th build) version doesn't, at least for me!
Also, have found this EXR that won't open in either old or new version of CIE, it was saved from the VFB. It will open in Photoshop. If I save as CXR, it will open in the CIE. Wow, I have gone acronym crazy :)
Attaching the EXR here for diagnostic purposes (I was just experimenting with Scatter and saving out to test bloom and glare while in there, if anyone wonders what the heck the rather random image is!) In the CIE, it opens as solid red, but opens fine in Photoshop (using the EXR-IO plugin there).
