Trainable Weka Segmentation works/lagging after updating FIJI


After updating FIJI, the Weka segmentation plugin works really slow (before I had no issue-it worked fine)-any idea how to return to previous mode. I have enough memory.
I tried restarting, checking through Debugging, using “JAVA_TOOL_OPTIONS” to make sure I am using memory allocated. I have Windows 7. One thing to notice is that through task manager of Windows, I can see the app doesn’t used the available memory.

I appreciate your suggestions.
