Cannot open, save, or print ship label on USPS website using Acrobat 11; Win 7; Internet Explorer 9.

Question

USPS tech and supervisor spent 1 hour walking me through fixes of uninstalling, installing and changing options to no avail. The provider software (USPS, Adobe & Microsoft) works using other browsers (Google Chrome and Firefox) but not with Internet Explorer (any version as I've tried it with 8 and 9). No virus, malware or defects in any of the software. This problem seems to reoccur every time there is a new release from Adobe, Windows Explorer or the USPS. Has anyone found a solution?
Specifically, either of the "print or save label" prompts in the online postage software opens a dialogue bar that give 2 choices: save or cancel.  The cancel option doesn't work at all; the bar stays open. The save option opens the operating system software to "desktop" but when the "save" option is selected there is no response.  No way to get out of the dialogue bar without closing the usps web site. Each time I've had to go into the account history file and claim a refund for the unprintable label. Options I've tried to solve issue:
>added usps.com to trusted sites in IE under tools
>enabled manage add-on for Acrobat Reader
>disabled protected mode in IE options
>unchecked "require server verification"
>uninstalled and reinstalled latest versions of Acrobat 11; tried Acrobat 9 and 10 installs
>did "repair" of Acrobat 11
>reduced security levels for IE and USPS web site
>uninstalled/reinstalled IE 9 and IE 8.
Each software provider claims the other's products are at fault, not theirs.

Thank you for your interest in my problem. USPS is the US Post Office.  Mailing labels can be created, paid for and printed on their website, usps.com. The labels are in pdf format and their application uses Adobe Acrobat Reader to open the file where the label resides and then print it.  Normally, you can  select either "print" or "save" to open the file where the label resides and then you again have the option to immediately print the label or save it to your "desktop."  I have printed or succcessfully saved  hundreds of these labels, despite changes in the various versions of Acrobat Reader, Internet Explorer (IE) and the USPS software. After returning from a 2 week vacation on Oct 1, I rebooted my PC to create and print some labels and the fun began.
The USPS software works perfectly until the print or save stage.  Using either prompt opens a bar in the lower part of the screen which then only offers the options of "save" or "cancel." ( So no way to print directly.)  If you attempt to "cancel" it does not respond - just starts the bar blinking a golden color.  If you attempt to "save," it opens to a screen to save to your desktop. When attempting to save at that point, the file will not save, there is no response.  The bar can not be closed, the save to desktop doesn't work, and there is no way out of the loop.  Even when closing or signing out of the website, the bar remains on the screen.  Only by closing and reopening Internet Explorer will the bar disappear.
USPS supervisor and tech persons claim the problem is with IE since their software works with other browsers, e.g. Google Chrome and Foxfire - which I have confirmed. It's just annoying and time consuming to have to exit IE everytime I want to create and print a label.  All other pdf files (whether downloaded from IE or created by myself) will print from IE using Adobe Acrobat Reader, just not the one associated with the USPS. What's astonishing is that the US Post Office doesn't mind that their program doesn't work with the world's most used web browser and they haven't been able to figure out why.  You would think either Microsoft (IE's publisher) and the USPS would want to do a fix.
I have scoured and tested all setup and setting options in the Adobe, IE, USPS software, including roll back to earlier versions and haven't been able to solve it on my own.
