I try to reproduce your issues, but cannot succeed

The first issue:

1. Open  http://cutesoft.net/example/general.aspx, remove all contents in editor area

2. Open Notepad

3. Input "this is a test" in Notepad

4. Copy "this is a test" in Notepad and paste it to http://cutesoft.net/example/general.aspx

5. Place the cursor directly ahead of "this is a test" and then press "Enter", one new line will be generated and the cursor is still in the first character of this new line. It is correct.

 

The second issue:

1. Open  http://cutesoft.net/example/general.aspx, remove all contents in editor area

2. Input "This is a test"

3. click button "Bold"

4. Place cursor directly ahead of "This is a test", and then press Enter

The strong tag is not removed.

 

Can you test it more and tell us which steps are different from yours?

 

Regards,

Eric
