Critical bug fixes

We invested a serious amount of time in resolving many of the critical bugs and I would like to share some of them with you:

  • Editor: Paste functionality in Firefox, Chrome and IE7 when ContentAreaMode is DIV.
  • Editor: When pasting a heading from Word, the Word formatting is not stripped in FireFox.
  • Editor: The inline spellchecker duplicates the content when there is a style tag under the content.
  • Editor: The Image Properties dialog is empty with floated element in Chrome.
  • TreeList: The Height property does not work correctly.
  • ComboBox and DropDownTree: The controls are inconsistent relative to their height of the input and the margin/padding that is set relative to the browser.
  • Dock: RenderMode=Auto results in a JS error and incorrect behavior of the control.
