The older Stand Alone version of HTML Editor or Form Builder uses CKEditor 3.5.6 which will not be compatible with IE 10.
In Data Bridge, the CKEditor version has been updated to CKEditor 4.0 which has been updated to work with IE 10, though CKEditor have released an update to 4.1 to fix some bugs in 4.0. We will be updating Data Bridge to include that version in the near future.
you can update the CKEditor Files manually.
in the webassist/ folder, rename the ckeditor folder to ckeditor_bak
On this page:
download
click the button to launch CK Builder. Select to use the Full Preset, and the Kama Skin.
Copy the downloaded CKEditor folder to the webassist folder in your site.
from the ckeditor_back folder, copy the following three files:
ckeditor.php
ckeditor-php4.php
ckeditor-php5.php
and paste them in the new ckeditor folder.
you will need to clear the browsers cache to see the updates take effect.
The KFM File Manger does not have an update to correct issues with IE 10. In the IE Developer tools, try setting the IE mode to use the IE8 engine instead of compatibility mode.
