I have a problem with R# 5.1.3 on Studio 2010 Premium, with Win7 x64, that has been there for a while (starting with R# 5 I guess). Sometimes (rather often, though) the content of the File Structure View is scrolled nervously up and down somehow. It seems like R# wants to constantly select one specific item in the view, and whenever I use either mouse or keyboard to scroll onto some other item then R# forces selection back to that "magic" item and in the same time I can often see that the thumb in its vertical scrollbar also fiddles a bit so the content of the view looks "nervous". I have of course tried to experiment with combinations of the options "Track caret in editor" and "Automatically scroll to source". It doesn't seem to help.
I use a Logitech "Hyper Fast Scrolling" mouse (MX 620). Don't think this is relevant though, since the problems is specificly on the File Structure View of R# only.
Any of you that have also seen this problem? Is it a known issue?
