I tried to test the bug on Demo Site http://cutesoft.net/example/general.aspx . It also happened.
Steps to re-produce:
1. Insert a Text Box
2. Delete text box by pressing key Delete
3. Press Ctrl+Z to undo but Undo doesn't work.
Please help me investigate what happened. Way to fix it if have.
Thanks in advance!
