[Mono-winforms-list] Issues in Undoing textbox values

[Jijesh]

Hi,

I have posted a bug report in bugzilla. 
Here are the steps to replicate the issue.

Test Application: create a c# winforms application containing two text boxes
in which, one is "multiline=true" and in other "multiline=false".

Steps to Replicate:
-------------------

Case 1 (TextBox with multiline=false): 

1. Paste some data(i tried the above test data) in the first text box.
2. select last few words in the text box.
3. click backspace or delete button to delete data.
4. again click backspace
5. press ctrl+z then it will throw error and application will also get
closed


Case 2 (TextBox with multiline=true): 

Follow the same steps as in Case 1.

The error i got is:

Case 1:

System.ArgumentOutOfRangeException: Argument is out of range. 

Case 2:

System.NullReferenceException: Object reference not set to an instance of an
object


My environment details: 

OS:ubuntu 9.04 
mono version: Mono 2.4+dfsg-4~dhx1~jaunty1 

Thanks in advance,
Jijesh V R
