Lately, I've been opening zvi files. It seems like after a period of time, Fiji becomes unresponsive to the channels dialog, and I have difficulty moving through stacks of the zvi file. This results in the program freezing. I have downgraded to other versions of Fiji, as well as reinstalling the program, and I still have issues.

It is probably an issue with Java 8 on OS X. One option is to downgrade to Java 6 for the time being:

Once things get slow, you can also try to obtain information about why it is slow, by following the instructions at:

This might help diagnose what is going wrong deep within Java, for example, which when followed up with a targeted web search will give ideas for working around it.
