Problem with ThreadAbort in App_Web_dlt0v2t4.dll

Hi,

I faced a problem in ASP.NET 2.0 where the application is retrieving data via OLE-DB and then suddenly it starting throwing TheadAbortException. Even though the application continued, but it seems a problem in the future at the back of my mind so if anybody can help with the below questions it will great. And the following is the Output from Output and call stack

Call Stack:

> App_Web_dlt0v2t4.dll!login.initialize(Object sender = {ASP.login_aspx}, System.EventArgs e = {System.EventArgs}) Line 23 Basic

Output:

Warning: Cannot debug script code. Script debugging is disabled for the application you are debugging. Please uncheck the 'Disable script debugging' option on the Internet Options dialog box (Advanced page) for Internet Explorer and restart the process.
A first chance exception of type 'System.NullReferenceException' occurred in comdat.DLL

An exception of type 'System.Threading.ThreadAbortException' occurred in App_Web_dlt0v2t4.dll but was not handled in user code

Questions:

1. Which process should I attach the debugger to find out what is happening in the App_Web DLL

2. The last message call before it falls into this problem is a Response.Redirect(), I do not see how it can happen... so if someone know more about this - would you kindly explain how this process suppose to happen

Many thanks!

Mark
