We use classic asp pages for our secure portal sites. 3-4 weeks ago a user indicated that a button (to be able to upload documents) on the page was greyed out and not accessible. The user was using Win7 and IE9. After some initial troubleshooting, we determine that using the compatibility mode in IE9 resolved the issue. Now yesterday 5 more users have reported the issue. The are using Win7 IE9 as well. We have setup test workstation and it is working fine on those workstations. All have upto date MS patches. Everything works fine in Firefox and IE8. The same is true of the users workstations. We use Telerik.Web.Design.dll and the Telerik.Web.UI.dll in this area of the page. Is there any known issue with these and IE9.
FYI-I am not a developer, but merely assisting our support department.
