VS 2005 IDE now unstable and crashing

I recently installed AJAX and the control toolkit, setup a sample website and it worked very slick. I have an existing app written in VB.net in VS 2005 that i am integrating the AJAX toolkit, specifically the dropdownshadow extender, scriptmanager and updatepanel, having copied the needed configuration into my web.config from the small app i wrote.

The problem is my environment is now extremenly unstable and crashes whenever i try to change a property of a control within the update panel or on any page containing an ajax control. Simply clicking on a textbox within the AJAX control will randomly cause an error screen i have never seen before saying Visual Studio has encountered an error and must restart.

Once the crash happens i cannot switch to design view as it says no AJAX tags are recognized, yet if i compile and run it works fine, not much help if i cannot design tho. I strip the tags out in code view and i am off again until the next crash.

After some crashes i try to drag an AJAX control onto a page and i get an 'Error: control could not be created' , control is not recognized. I have to reboot my system to get it to work.

I installed SP1 Beta and the problem still persists. This is very frustrating as the controls are working great other than when they crash my IDE. I will attach a screenshot if needed once i get in front of my dev station.

Hopefully someone has had this problem already.

Cheers!! And great work so far!!

I have never seen that, but can be a bug fixed in the new SP1 for VS2005http://alpascual.com/blog/al/archive/2006/12/15/Visual-Studio-2005-Service-Pack-1-has-been-released.aspx

See if installing it fixes your problems

This happens to me much more often as well after installing AJAX.

Sorry been away for a while, i installed SP1 but still unstable. I also constantly get

Error 182 Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.

It does not occur everytime but when it does i cannot change to design view. The site still runs fine but it is frustrating that i have to reboot or wait for the 'magic' in the air to sort the problem out. I have seen this in many forums but no one ever has an answer yet.

VS2005 often crashes when I try to shut it down with SP1 and SP1 for Vista. I get memory corrupt errors and it can't recognize the ASP.NET Ajax tags most of the time. I am running Vista x64 RC1 though so some problems could be related to that...
