I've noticed a bizarre issue where I click on one server in the browser and another server will become highlighted as if it had focus. If I click on the server I want again, both will be highlighted as if they have focus, but the highlight on the server I want disappears after a short period of time. Double clicking on a server is fine.
We've made a pass on some focus- and scrolling-related issues in the server browser, and those should be in by the next update. Do you remember if you had sorted the browser by clicking on a column before this happened?
Regarding scrolling issues in the server browser.. do you mean scrolling will actually scroll now instead of changing the selection?
