User(s) can reproduce this bug
When I edit a .htm file from Solution Items, it takes 1-10 seconds before the text being typed is actually displayed. This is a C# solution with 20 projects and a simple .htm file in a Documentation folder under the root of the solution.
Details (expand)
Product Language

Version
Visual Studio 2005 Team Edition for Software Developers
Operating System
Windows XP Professional
Operating System Language
English
Programming Language
C#
Technology Area
Visual Studio 2005
Steps to Reproduce
Add a .htm file to solution items, or add existing file to the solution items. Open the file then click to edit. Start typing. Notice the delay. Click on the Solution Explorer, then back to the .htm file and type away. Backspacing and deleting are slow as well. (Use a 500 line .htm sample file with few <hr>, but no css or links.)

<html xmlns="http://www.w3.org/1999/xhtml" >
Actual Results
All editing is slow. It is as if something else is going on in the background, then it catches up.
Expected Results
Normal editing as with a .cs or .vb file.

What type of project is the html documentation file in. Is this in a C# client project or a web site?
Did the performance chnage after sp1?

It's a c# solution with 20 projects including a web site. I uninstalled, reinstalled VS2005, then SP1 and there is definately a performance increase with SP1. The only thing I can think of is that I may have had WAP installed when I first reported this issue. By reinstalling from scratch SP1 seems to be much better...

But there's something else weird happening with Solution Items, with and without the webproject in the solution.

1) Create a new solution within an existing web project...
e:\website\application1
e:\website\application1\solution2

2) add a doumentation folder and an emtpy .htm file
e:\website\application1\solution2\documentation\welcome.htm

3) Add existing file to solution2|solution items, then open the file using Solution Explorer.

4) Now add the existing website project to the solution.
e:\website\application1 (http://localhost/vdir1)

5) Using the Solution Explorer, open Solution Items|welcome.htm and it expands the web project instead...

6) Double click (again) on Solution Items|welcome.htm (expecting the window to be selected)...
Error: This document is opened by another project.

7) Remove the web project from the solution.

8) Open Solution Items|welcome.htm and it works as it should.

Obviously the Solution Explorer opens Solution Items files in a different way when a web project is included in the solution, which may explain the difference in operation.

The editor's performance was improved by changing the default behavior of the Property Grid to not show properties when in source view. This default can be change by selectung Tools->Options menu item, selecting the Text Editor -> HTML -> Miscellaneous Page, and checking or unchecking Enable Property Grid in source view option. As for the second problem you reported, we will investigate it.

Thanks,
John
