scrollbar disappears for txt, html, cshtml, aspx, asp files

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create new txt/html/cshtml/aspx/or asp file
2. observe error message is displayed and the scrollbar disappears. Error 
message from activity log:

System.Collections.Generic.KeyNotFoundException: The given key was not present 
in the dictionary.

IOutliningManager outliningManager, ITagAggregator`1 changeTagAggregator,

factory)

Microsoft.VisualStudio.Text.Utilities.GuardedOperations.InstantiateExtension[TEx
tension,TMetadata,TExtensionInstance](Object errorSource, Lazy`2 provider, 
Func`2 getter)

What is the expected output? What do you see instead?
I expected to see the scrollbar (any scrollbar).  Instead, no scrollbar is 
displayed.    

What version of the product are you using? On what operating system?
ProgressiveScroll 0.6.1
VS 2012
Win7 64-bit

Please provide any additional information below.
Even if the color coding isn't supported for this type of file, reverting back 
to the original scrollbar would be better than having none at all.

Agreed.

It shouldn't happen for txt files since they don't have ContentType == "code" 
and I can reproduce it for html files. So I should be able to come up with a 
fix.

I found the problem with html files. Now I just need to find an acceptable fix. 
Should be ready this weekend.

Should be fixed in 0.6.2.
It was crashing on the highlight system. So I disabled that for now.
