Restart of VS solves the problem, indeed.... Or at least until the next time it happens.
Our observations are that the popup menus (WPF based) don't get redrawn properly in cases like the ones we've mentioned here in this thread (resume from sleep/hibernate, work through RD or on a VM). We'll try do dig deeper into that as the issue seems quite annoying. Until a proper fix is found, restart of VS is the only workaround there.
Thanks for sharing your experience on that one.
