Description David Protter 2015-11-10 12:02:35 CST
I think this issue started when I upgraded to El Capitan, but it may have been when I updated to Java 8. In either case, there are a lot of little issues. I've seen a few of them in the forum.

1) Clicking the FIJI icon in the dock opens up a new java instance. I can't drag and drop files onto the instance.
2) metadata is no longer parsed correctly from our DV files (DeltaVision)
3) Often, when clicking from window to window I lose the all of the menu bar disappears except for the ImageJ menu. It can take a while for it to come back. 
4) performance is very slow and seems to deteriorate over time. Sometimes it will take 30s just to responde to changes using the brightness/contrast tool. (opening the bug report form took ~1 min)

Thanks for your help!

Thanks for the report, David.

Other users on the ImageJ forum have been discussing this recently. In particular, see this thread:

There is no fix or workaround yet other than to revert to Java 6 for the time being:

I think the issue is Java 8 rather than El Capitan. At least: others have reported the problem under Yosemite as well.

In any case, these same problems were already reported as 1114, so I'm closing this as a duplicate. But don't worry: solving this problem is very much on the radar.
