Have an ASP page using AJAX - have embedded the latest Microsoft Report Viewer control. The page access various SSRS reports. The application works fine for most users, but in certain cases, the toolbar wraps and occupies about ten lines - using about half of the visible area. Users affected by the problem are using IE7 and IE8. When the toolbar is distorted like this, the buttons (Page, Export, etc) also seem inop.
The problem does not seem to be related to the RDL; either all the reports work or none of the reports work.
Can this be a browser settings issue? Something with the .Net framework?
