title: Bug ToolBar Report Viewer
body: <p>I'm working with a report RDLC with a chart, in my asp.net application. 
  Everything was ok, until my ReportViewer toolbar started  this strange behaviour. Every button got a entire row space, then one toolbar becomes five bars with one button each.</p>
  
  <p>I compared my font with a backup made one day before, and I didn't find any change that could cause this. Anybody have a tip? </p>
