Instance highlighting not working in Monodevelop 4

I’m trying to get the currently selected variable instance to show up with a highlight in the newest Monodevelop 4.0.1 with Unity 4.3.
This worked in the previous version before I updated.

I’ve tried turning on Text Editor | Syntax Highlighting | Semantic Highlighting, but that didn’t help. As well I found more bugs while trying to change colour schemes (bg colours won’t get saved on the semantic variables, and importing styles with bold&italic fails).

Does anyone know any other way to get the variable under the cursor to highlight all instances? Or even an extra plugin that will do this?

Thanks.

Tools → Options → Text Editor → Markers and Rulers → Highlight identifier references

it highlights on the Taskbar, but does not flip you over to the Mono app. You have to Cool Switch or or click on the highlighted icon on the taskbar.
…thus why Mac is better?

for Mac
MonoDevelop-Unity > Preferences > Text Editor → Markers and Rulers → Highlight identifier references
