I have a dual display setup. Visual studio crashes consistantly when I try to bring the find/replace panel and the results panel to a second monitor. No project or solution needs to be loaded to reproduce the problem.
See steps to reproduce below. Interesting thing is that it only crashes the first time when docking left/right. Top/bottom doesn't crash at first, unless you then move it and dock again, then it crashes the second time.
Either way, it seems to be quirk in the window docking part of VS.
