It appears to be background processing in the editor, but the explorer
will not open filesystems or jar files while it's happening.  I could
also look at the menus, but when I chose the options menu under tools,
i did not get anything under options.  Also, when right clicking in
the explorer, and choosing new, there were no options to select (it
said "empty").

After it went to about 216MB usage, the processor did go back to 0 and memory stopped growing.
It seems to be usable now.
