Adobe Reader SLOW/Locks Up

I'm running Windows Vista and for over a year now Adobe Reader (8 or 9) run very slow. Whenever I zoom, pan, or scroll it will take 100% of the CPU for a minute or more before the screen actually moves. If I touch anything in the meantime then the program stops responding. Any help is greatly appreciated!

HT2506 I prefer Preview as my default reader. Somehow Adobe Reader has locked itself as the default. How do I reset back to Preview?

I prefer Preview as my default reader. Somehow Adobe Reader has locked itself as the default. How do I reset back to Preview?

First order of priority - Establish what platform is in use. In this case: MacBook Air with Trac Pad, no Mouse.
Second - Establish Operating System in use. In this case: OX 10.8.3.
Third - Establish, as best as you are able, the parameters in which you have been attempting a work-around and, to include mention of, any other secondary software program capable of becoming a default other than, in this case, Preview.
Fourth - State the problem: Adobe Reader somehow automatically has become the Default PDF viewer.
Here's my answer: When a trac pad not a mouse is in use - Select the PDF you will be opening; don't open it, Select it. At this juncture, tap COMMAND - I (Unfortunately Apple has no Drop Down Menu motion to achieve this operation that I can determine); at this point you will get this:
Click on "Open with: " If you see Adobe Reader there in lies the problem. So, simply click the "up/down" arrows on the Selection Window, and from there click on Preview. From there on Preview will be your Default program.
Thank you to everyone who helped in reply to my initial query.

Adobe Reader is locking up Windows 7

Good morning all,
I have been doing some digging on this one and have had no joy so far. We are deploying Windows 7 in our office and I have one user, and only one who is having problems.
They had Adobe Reader X installed and they began to have problems with it after they were upgraded to WIN 7. When they went to print a PDF it started to lock their PC for 3-5 minutes after which they were able to continue with their work.
This behavior is internmittent in that it does not happen with every PDF and typically only happens once a day. Some times it is the first PDF of the day, sometimes in the middle of the day, but once it happens it does not happen again in the same day. Sometimes the user does not experience the problem for several days. We have been unsuccessful in determining any pattern or any particular in which this users machine is environmentally different from any other users machine.
No other users are experiencing this problem.
The user has a laptop and shuts it down to take home each night and starts the box fresh in the office each day.
Lately this behavior has extended to when the user just opens a PDF. Their laptop will freeze for 3-5 minutes and then they can continue with their work.
Based upon a very few articles we have found on the subject, we have tried a couple of things without success:
We have tried clearing the Adobe Reader cache
We have uninstalled Reader X and replaced it with Reader 9x
We are hoping that someone out there who has seen something like this before and can suggest some environmental or proceedural thing that we have missed. This one is driving us crazy.
Thanks in advance for any help.
Steve

Yeah, I've been having similar issues. Each time it happens, it lasts for about a minute. Afterwards, I can go on and do other things for a while, but it doesn't last long, and I get another minute-long stall. This happens on every website. It wasn't easy to find the report that matched my complaints exactly, so I'm worried that this is only a problem with a few people. It even stalled while typing this...

Adobe Reader X Locking Up or Not Launching

Windows Vista® Home Premium with Service Pack 2 (32-bit and 64-bit)
Processor: Pentium Dual-Core CPU T4200 @ 2.00 GHz.
Memory (RAM): 3.00 GB
System type: 32-bit Operating System
Over the past several months, Adobe Reader X has been locking up after openning a .pdf file. The file opens, fully visable as normal, but locks up - "Not Responding" - when I take any action (page down, try to print, etc.). I uninstalled and downloaded a number of times as the first fix attempt and encountered the following. (1) When selecting a .pdf file to open, the Adobe Reader title page opens, but then immediately locks up. (2) When selecting via the shortcut or Start Menu/All Programs/Adobe Reader, the program does not launch and the following error displays: Fatal Error: Acrobat failed to connect to a DDE server. I have enjoyed the use of Adobe Reader since 2007 and find this frustrating and disappointing. Please advise.

The latest download for Windows Vista is 10.1.4; update it using Help | Check for Updates, or download the update from Adobe - Adobe Reader : For Windows : Adobe Reader 10.1.9 update - All languages
To apply the registry script:
download protected10.zip and save it to disk (e.g. your Downloads folder)
using Windows Explorer, double-click on the downloaded file; it should open and reveal protected10.reg
double-click on the protected10.reg file to execute it

Why is adobe reader slow after installing windows 8

(B) Try reset all settings
Settings>General>Reset>Reset All Settings
(C) Setup as new (data will be lost if you do not have backup)

Adobe Reader X locks address bar and search box in Firefox

Hi all,
I've been using Adobe Reader X in Firefox 3.16 and I've just noticed an interesting "feature".
When reading a pdf from the web, Adobe Reader locks the address bar and search box so you cannot type a new address or search using the google search box. It just won't let you enter any text. Even on opening a new blank tab. Has anyone else come accross this and is there a fix? Cheers.

Oh it was a problem with Adobe's Plug-in. As per [https://support.mozilla.com/en-US/questions/804580#answer-167069 MrKoffee's answer ], I noticed that I already had Adobe Reader X installed but nevertheless I went to adobe.com to download it again. When I installed it this time, it said "installing updated patch". Went back to Firefox to check and problem solved! :)
Ps. did not need to disable any previous plug-in or even close Firefox.

Adobe Reader slow when mouse wheel scrolling in Full Screen mode.

When I scroll a pdf in normal mode, its fine, but when I try to view in Full Screen mode, the scrolling is much more slower and it takes more rolls of the mouse wheel to get to the next page. Does anyone know how to improve the scrolling function of the Adobe Reader when viewing a document in full screen mode?

Good that you solved your problem. There will probably be other users that need to solve the same problem and your solution might help many others. The support here comes from users helping other users.

Adobe Reader 9 locks up on certain files

I'm running Adobe Reader 9 on an XP machine. Most pdf files are fine, but some are having peculiar behavior. Someone has sent me pdf files that they've created from Excel 2007. If I try to open the file (via double clicking the pdf file or opening the Adobe Reader and using the File-Open options, the software freezes and no longer responds. I must kill it via the Task Manager.
After some attempts at troubleshooting, I've found a peculiar workaround. If I open the reader software, then change *anything* in the configuration (i.e. changing absolutely anything under preferences), then it will open all the files just fine after that. If I shut down the Adobe Reader and restart, it will not open these files successfully until I do the above workaround.
Anybody know how to fix this? Very strange.

Bump!

Adobe Reader program uses huge memory in OS X. How to reduce it or any settings to change?

Lately I started to do alot of research on paper works for University projects. Most of the downloaded papers are based on .pdf extension. As usual, I read these files via Safari or open it separetly via Adobe Reader itself.
While working on Papers, I noticed that my machine's memory spiked to 7 GB ++ almost reaches 8GB of memory usage. This is unusual. At one point, I ran Java programs and simulatenous opened up many pdf format files format on my safari browser, it went unresponsive and unable to use keyboard & trackpad. Had no choice, had to hard reboot.
Contacted Apple support and reported the issue on unresponsive to them. They provided following KB to troubleshoot further:
http://support.apple.com/kb/HT1379
http://support.apple.com/kb/TS4636
After that, I never encounter unresponsive issue but I have question Adobe reader program. This program uses huge amount of memory and I would like to know if there is anyway I can reduce the usage of memory of Adobe reader. Or is this normal?
Also, had an issue with pdf page scrolling, it is very slow.
Thank you,
Soma

Add on .. In Adobe Reader go to View > Page Display > select Enable page scrolling. This helps to improve adobe reader slowness. But, just a workaround. Not a solution.
Also, untick "use page cache" under preferences.

Adobe Reader 10.1.4 Lock-Ups

Hello,
When our campus users launch Adobe Reader 10.1.4 after logging on to a campus machine via a network account (with a re-directed app data folder) and launch a PDF from a network location by double-clicking it from Windows Explorer, Adobe Reader will launch, but then lock up and enter a "Not Responding" state after a few seconds of working with the PDF. I can only reproduce this issue with both the Enable Protected Mode at startup and the Show me messages when I launch Reader boxes checked (if either box is unchecked, the lock-up does not occur). If I wait long enough, sometimes, the "Not Responding" state will end and I will be able to view the PDF without issues. However, after a single reboot, the problem re-occurs. Our campus machines are on the 32-bit Windows 7 OS.
I have been able to reproduce this issue in Adobe Reader 10.1.2, 10.1.3, and 10.1.4, but not in Adobe Reader 10.1.1. I am not able to reproduce this issue using a local account opening a local PDF, a local account opening a network PDF, or using a network account to open a local PDF. The issue also does not occur if the user first launches Adobe Reader, and then opens the network PDF using File->Open. In other words, the issue only occurs when a network account opens a network PDF by double-clicking on it from Windows Explorer.
I did some research in the Adobe Reader forums, and here are the workarounds that I found and my success with them:
1) Uncheck Enable Protected Mode at startup
As I stated before, this does work around the problem, but also decreases security. As a troubleshooting step, I tried using the Adobe Reader documentation to white-list everything that Protected Mode was 'blocking'. The lock-ups still occurred even though the Protected Mode log was empty (after whitelisting) and did not indicate that anything was being blocked.
2) Disable Enable Hardware rendering for legacy video cards
This workaround did not work for me, even after disabling the legacy video cards and switching the preferred renderer to software.
3) Uninstall and reinstall Adobe Reader
This workaround was also ineffective.
4) Uncheck Show me messages when I launch Reader
As I stated before, this does work around the problem.
But these are not fixes - just workarounds. Does anyone know what the root problem is and whether or not Adobe will be addressing this issue?
Thank you in advance.

Hi, I can't offer any solution just agreements that it isn't just yourselves but others shared experiences:
The lockup began several years ago and subsequent versions of Reader have not altered the lockup problem one bit.
Typically the whole program loads, as does the document (it doesn't matter which PDF, any and every PDF cause lockup), you have about 4 seconds to scroll down or whatever action then... application completely freezes, states "not responding" and usually it remains entirely locked for at least 1 to 2 minutes while it hogs majority of system resources. When it releases, program again fully responds. Closing and reopening only repeats the same bad user experience.
Uninstalling, reintstalling, new versions, have no effect. Inevitably, the main result is to use PDFs significantly less as it is not worth it, yet ultimately it is unavoidable for documents.
Following your 1,2 and 4 has reduced lockup time to around 50 seconds but still not acceptable for regular use. This reduction and the fact that earlier versions on the same system platform worked 100% fine suggest to me it is additional (and for many users, entirely unecessary) Reader functionality such as trying to get messages, check updates (another to turn off), etc. that halt the software from working smoothly as it should rather than any problem with the host system.
I'd be very surprised to hear Adobe are unaware of the problem as there are many messages about this from a search and yet seemingly no definitive solution as far as I can find.
I too will recheck here in hope of a solution emerging.

After completing my upgrade to Adobe Reader 11.0.10 When I attpemt to use "Tools/File/File Save As" from IE 11 I get a "Adobe Reader is not Responding" and my browser is locked up.

After completing my upgrade to Adobe Reader 11.0.10. when I attempt to save an online PDF to my local drive I receive a blank window where I would expect to see file directory structure to save to.
No local directories are displayed for "Saving To", it is all blank. When I try to Close (by clicking X) the "File Save As" box a message pops up on top that says "Adobe Reader is not Responding" It locks up all of my IE windows, not just the one with the PDF doc.
I then need to go Task Manager and stop the IE task. All my browser windows are then closed.
That is the only way to recover from the "Adobe Reader is Not Responding" message.
This was not happening in previous versions of Reader.
Tolls/File/File Save As always worked properly.
I have installed IE 11 (11.0.9600.17690)

Please don't post the same question multiple times!

In Adobe Reader (v11.0.09) locked/froze after signing and can't access my full fill-in answers to edit

In Adobe Reader (v11.0.09), after answer application questions in scrolling window panes within a .pdf doc, I signed the doc, and it froze/locked, so I cannot edit or view the full answers anymore. On an ugent deadline, so any thoughts on how to re-access my full answers within the scrolling window panes in a .pdf doc? thanks!

Hi Paix,
It is normal once you sign a document it considered to be a complete of yours. So no one shouldnt make any change after you signed the documents gets locked.
You can get idea from this doc: https://acrobatusers.com/tutorials/how-to-lock-form-fields-using-a-digital-signature

Scrolling through PDF files is slow using Adobe Reader on MY MACBOOK pro with retina

Scrolling through PDF file using Adobe reader on my MACBOOK pro is very slow and stuters. That is even for small files. MAC preview and Adobe pro do not have this issue. It is only Adobe ready.
Please advice.

Summarizing the problem specifics and versions for future readers:
There are two separate "slow scrolling" bugs in recent versions of Adobe Reader on Mac OS X. Symptoms: scrolling by mouse or fn + down arrow is very sluggish and laggy. It is not isolated to large or graphically complex documents. This 2 megabyte PDF shows illustrates the problem: http://www.hq.nasa.gov/alsj/nasa-tnd-6846pt.1.pdf
Problem 1: Adobe plug-in for Safari causes slow scrolling when viewing PDF documents within Safari. Solution: remove Adobe plugins from Mac HD/Library/Internet Plug-ins/AdobePDFViewer.plugin. I also deleted AdobePDFViewerNPAPI.plugin. This will cause PDF display within Safari to revert to the built-in Apple PDF renderer, which is very fast. These files will be re-installed anytime you install or upgrade Adobe Reader.
Problem 2: Stand-alone Adobe Reader scrolling is slow starting with version 11.0.01. Version 10.1.4 and earlier are not slow. User CF McBlob did not experience this slowdown, but was also running Acrobat 10.1.7, which might have libraries which prevented the problem. I'll do further testing when possible to try and isolate more details.
Platform specifics: OS X 10.8.4, late 2012 iMac 27", i7 3.4Ghz, 16GB RAM, 3TB Fusion drive, GPU = GTX675MX, 1GB

Adobe reader really slow on brand new Core-i7 machine

Opening of a PDFs is very very slow on my brand new Windows 7 64-bit machine. Machine is a new Core-i7 system with 16Gb Memory
PDF's which open on other much older pc's within a second take 20-30 seconds on this new machine.
The machine has a Radeon R260 Graphics card which was used in the previous machine with no issues. Just to be sure I have removed the card and used the on-board graphics to try to eliminate the card but the problem is exactly the same so must be windows related.
Reader has been uninstalled and re-installed with no Joy.
The rendering of the image is a problem as when zooming or panning the image again redraws very slowly (20-30 seconds) each time.
PC is otherwise very fast.
Can anyone help ?
Thanks

Hi VS2015,
Have you noticed this issue with any other program too or just with Adobe Reader?
How much on-board graphics memory do you have on your system?
Moreover, As you had mentioned that "The rendering of the image is a problem as when zooming or panning the image again redraws very slowly (20-30 seconds) each time." I would recommend you to Update your Video Driver from Device manager option in Control Panel.
Regards,
Rahul
