Description Meng Xin Zhu

2011-06-14 04:02:09 EDT

I'm using Indigo RC4 on Ubuntu 11.04.

After I inputed some java code, the content assist opened the context menu of some suggestions. It's an intermittent issue, I met the same issues several times in a week.

The eclipse hangs after the suggestion menu is shown.
