The context menu of VAX has an entry called "Browse Symbol" which is enabled when the caret is on any symbol. Clicking on it does, well, nothing. Never.
"Browse Symbol" is a remnant from VA.NET 7.1. If we are correct, the command used to open a small, undocumented window for browsing. The window was the precursor to our HCB.
Problem exists for VS.NET users only.
In all likelihood, we will remove "Browse Symbol" from our context menu when we revamp the entire menu.
