Turn off Automatic switching to project tab when clip is added to timeline.

Hey, this really annoying thing has started happening in my Premiere Pro.

I have my media browser tab showing with the project tab beside it in the same little dock. Whenever I drop a clip into the timeline it automatically switches to the project tab. Then I have to click back into the media browser to find other clips. And again when dropping one in it will switch back over.

This has only started happening in the last few weeks and I cannot find a setting anywhere to change it.

Any help is greatly appreciated.
