Stating that you're using the "latest version" isn't as helpful as giving us the version numbers.
- What version of MB are you using?
- To clarify, are you using the visualizer plugin, or the visualizer that comes with MB. If the later, which one are you using? If using a plugin, create your bug report on the thread for that plugin so the plugin developer can see it. And include all the info I'm requesting.
- Does MB crash every time you open MB? Or only when you enable the visualizer?
- Are there any entries in the Error Log (Help > Support > View Error Log) from the time you had the crash? If so, copy and paste it here.
- Please post a screenshot of the entire MB window so we can see how you have it set up?
