Acrobat XI unstable on Win7 and Win8

Anyone else having trouble with creating/appending a webpage from browser to a PDF.

Typical problems:

1. firefox crashes during creation
2. Creation popup window keeps running with no progress
3. Error popups "DDE unable to communicate with Acrobat"
4. In ability to capture Web pages that have JavaScript
   ( The most frequent language on the web;  Acrobat has JS built in )
   When this happens, I stop having the browser append the page,
   and instead request the page be appended from Acrobat.
   Serious Flaw:  If the page I'm viewing was arrived at by Single Sign On
   to the site, Acrobat will only collect the signon redirection page.
   That is why appending the page from a logged in browser is important.
5. Most annoying:  Acrobat does not remember the name of the last PDF used.
   It always truncates the name into something unusable.
   I have to ALWAYS find the last PDF I was writing to for a new "Append" request
6. Acrobat becomes non-responsive when DDE connections fail.
   It means I cannot launch Acrobat at all ... even for different pdf files.
   Solution:  Task Mugger and kill the running Acrobat processes.

I have several Acrobat dmp files ... I opt-in to "make Acrobat better" ... is Adobe

getting these crash failures?  Something more I have to do at my end?
As far as I can tell by dates, the crashes had nothing to do with Task Manager kills.

I see the same problems in both Win7 and Win8.

Acrobat X worked much better ... but the plugin was only available for Internet Explorer,

so I upgraded to XI.

Super annoying:  Adobe does not appear to ever have tested appending from a

browser to a PDF that was just created.   It always presents a corrupted filename

for selection.

My Solution:

Create an entirely new directory

Place the pdf I want to create there as the only file

When Acrobat "forgets" the filename, it does still remember the directory

and I don't have to search for the PDF I want to append to.
It still is an additional keystroke to select the file ... which really slows me down.

Please fix these things.  Or do I have to wait for XII version to get any fixes?

I am using Acrobat XI Pro Version 11.0.06
