Labview 2009 SP1 crashes when moving large selection with arrow key

If I select a lot (10 or 15) of Block Diagram components and try to move them some distance with the arrow key, I will frequently get a program crash.  Since a smaller number of components seems to crash after a longer travel distance, it looks like some kind of buffer overflow error.  I do not see this problem when using the mouse to move selections.
I have checked to be sure I have the latest video driver for my NVIDIA Quatro FX570.  I have also tried working with no hardware acceleration and no combined writes.  This is happening on Windows XP SP3 with all the current updates.
It has become so bad that I have to do a Save As every fifteen minutes to keep from losing data.
Why don't I use my mouse for all movements?  Because it is not as accurate and not so easy to restrict to one dimension of movement.   My hand is not as steady as it once was.
I hoping someone will have a suggestion that will clear up this problem.
Solved!
Go to Solution.

As I indicated, I had the same problem with 8.5 and just DID a new installation of Labview 2009.
Since it is possible my three-monitor setup, which obviously requires more video memory, may be at the root of the problem, I am satisfied with the workaround of dragging the objects near their final destination and then using the arrow keys.  
Three monitors are ideal for front panel, block diagram and Help/Internet/Probe Window.  When I had to work in the field with only one monitor, I felt severely handicapped.
You may consider the matter closed.
Thanks for attempting to duplicate the failure.

  • Keynote Crashes When I Move Objects With Arrow Keys

    Subject explains it all.
    This happens on both my 2.4GHZ Intel iMac and G4 powerbook.
    Machines are running OS 10.5.2 and Keynote 2.0.2
    I've bought both Leopard and Keynote and installed all the software from the CDs.

    The advice I would take from the last post would be used only to isolate the issue as it might relate to a system wide issue or a user specific issue. In other words, can we determine Keynote's behavior as being related to your home account and those files in your folder or the System (OS) level files? Read on please…
    If, after creating a new user account and logging into and Keynote continues to behave the same way, then potentially there is file outside your homefolder responsible for this. The file in question would, I'm sure you would agree, be a file related to Keynote's functionality and is accessed while Keynote is in use.
    When Keynote is attempting to follow your instructions it may be accessing a file that it relies on.
    A program which you can download to troubleshoot the issue is called appzapper, you can visit the developer's site here: http://appzapper.com/
    My suggestion would be to download this little app. Install it>drag and drop Keynote onto AppZapper. AppZapper will do its' best to find files relevant to the Keynote application and give you an opportunity to trash them.
    If you are curious as to the files AppZapper associates with Keynote, copy the name of those files and do a Google search to find out more about those files.
    In most cases the list of files, AppZapper associates are harmless if trashed, just make sure Keynote is not open while doing this or Keynote may sort of ask itself what is going on and behave oddly, a quit and relaunch should fix that if you forget to quit Keynote.
    Good target files that AppZapper might find are what are known as .plist files, plist as in PropertyList. .plist files typically store application preferences. So if you have ever gone to the preferences for Keynote in this case and modified the settings that .plist file would have stored those changes you set. If you move the .plist files to the trash, Keynote, upon a relaunch will say to itself, oh look, my .plist files are missing and simply regenerate those .plist files.
    The point here is if the .plist files were corrupt and Keynote was accessing those file(s) it would try to read the file and say to itself, hey I don't know how to read this and in this case, shut itself down.
    AppZapper may find more than just .plist files, investigate any files you feel hesitant to trash using your our old friend Google to learn about what it is you are going to trash.
    In most cases what AppZapper finds is safe enough to trash, just be sure to close Keynote before running this to keep Keynote from running into any unexpected surprises. It would be like yanking candy from a child's hand - that wouldn't be too nice.
    Finally if the issue persists, using DVD1 that came bundled with your mac, you should be able to install the bundled software only.
    Reinstalling Keynote or iLife should also be considered as a solution.
    An entire OS purchase or OS re-installation is definitely overkill and not an elegant solution, not to mention the downtime.
    The solution I am proposing hopefully makes common sense to you and gives you an overview in terms of understanding that there are files other than the application file related to any application's overall function.
    AppZapper is a small download and may help you locate that stubborn file causing you grief.
    That being said, creating a new user account on your mac and logging into it to isolate issues as being system wide or user specific is indeed the way to go to isolate issues in those terms.
    Keep us posted.

  • Moving anchor point with arrow keys crashes Photoshop CC

    Hey guys,
    I've recently run into this bug many times while working with shapes. Don't really know what initiates it but it's super annoying as it crashes the PS CC completely without possiblity of recovering the unsaved files.
    The bug appears while working with shapes after file is saved and reopened. Because I use to design pixel-perfect UIs, I work with arrow keys a lot to be sure every pixel is in the right place. So after selecting one or more anchor points of shape and hitting any arrow key (to move it by pixel), photoshop immediately crashes with this super-long description of bug: http://justpaste.it/ccshapecrash
    Dunno why but this occurs very often when handling 1px-thin rectangles.
    Is it only me or has anybody else experienced this as well? Any idea what exactly is causing it or what might be wrong with my config?
    Never seen that kind of error in Photoshop before. It completely destroys my everyday workflow

    I have exactly the same problem and I don't have any solution. I was tried to update the latest video drivers - nothing! Tried to update Photoshop which updates fixes bugs - nothing! The problem continues.
    My OS is Windows 8 64bit, video card Nvidia GT 630. For the case, my Photoshop 32x works better (faster) than the 64x. Why is that ? I hope to have a solution.

  • Moving Movie Clips with Arrow keys

    How do i make it so when i click the left arrow key, it will
    change the movie clip to make it turn around?

    Yes, that's what the code I gave you is intended to do....
    you replace that code with whatever action you need to take to turn
    your movie around.
    I have no idea what your movieclip is doing, but I'm guessing
    by your response that if it was an arrow pointing left to right
    (just an example), you want it to be pointing right to left when
    the left arrow is pressed. If you want an immediate turn around,
    then the simplest way to do that is to have another frame
    containing the movieclip that it moves to where it faces the other
    direction--and to have it appear turned around, from the toolbar
    you select Modify -> Transform -> Flip Horizontal.
    So the movieclip would live inside another movieclip that has
    two frames with stop()'s for each frame. In the first frame you
    would have the subclip facing left to right, and in the second you
    would have it facing right to left. If we call that 2-framed
    movieclip "walker", the code I provided before would
    become...

  • Bigger "step" when moving bd stuff with arrows

    Sometimes I will make something like a loop considerably smaller and now I want to move things outside the loop directly to the left/right. I will highlight everything and use the arrow keys which automatically shortens the wires as things move (I believe) and doesn't just tuck the "excess" behind other objects. However, using these arrows the bd stuff moves in very small steps. Is there a way to make it shift in larger steps? Sort of the LabVIEW equivalent of pressing arrows in text editors moves your cursor letter by letter, but certain key combinations can move the cursor to the end of the word, or line.Or is my best bet to highlight, drag with the mouse, then use up/down arrows to straighten anything out that may have become bent?

  • Moving Identity Plate with Arrow Keys

    I have always been able to move my identity plate around using the arrow keys. For some reason, it doesn't work any more. I am using Lightroom 2.3. I know that this is a small problem, but I sure would like to know how to remedy this. Thanks!

    Hi Ken,
    This is how I have done it.
    1. Create identity plate in Illustrator and save as an Illustrator file = .ai
    2. Go to Overlays in Lightroom and check Identity Plate
    3. Within the Identity Plate checkered box, you will see a pull-down menu on the bottom right
    4. Select Edit
    5. Select the radio button: "Use a graphical Identity Plate"
    6. Locate the ai file and select Choose (You might not see anything in the window, but don't worry about that
    7. Select Custom
    8. Choose Save As and give it a name
    9. Select OK
    Now, when you go into that checkered box within the Identity Plate window, you will now see your new Identity Plate (ai graphic) listed. Select it, and it will be displayed on your photograph. Sometimes, I have to select it twice (not sure why) for the resolution to be high quality. Good luck and let me know how it works out.

  • Moving a line with arrow keys/can't adjust distance

    In Illustrator CS6 I can't adjust how far a line moves when I move it using the arrow keys. I've gone to Preferences>General>Keyboard Increment and changed the amount, but the line moves the same distance no matter what I put in. Neither Snap to Grid nor Snap to Point are turned on.

    Thank you Mike! It was driving me crazy. I just started to use CS6 and hadn't messed with any adjustments. How would someone know to check such a seemingly obscure--except to come to the forum?

  • Illustrator CS6 (Mac) crashes when opening large documents with drop shadows

    I have a Macbook Pro ver. 10.6.8 i7 Core, 8 Gb Ram, and I am running Adobe Illustrator CS6.
    I have a document that is 18" x 42" and contains drop shadows. It was created using CS6.
    When I apply a graphic style (gradient and drop shadow) It has a progress bar that says "Drop Shadow" and it fills up and freezes. I recreated the document, and I am having the same issue repeatedly.
    In order to do what I needed, I had to ungroup the letters recieving the graphic style and apply it to each letter individually. If I try applying it to more than one object, the freeze happens again.
    I saved the file I created, and now I can not open it. On load it has a progress bar that says "Drop Shadow" and it fills up and freezes.
    I can open the same document in CS4 on the same system with no issues, it takes less than 5 seconds to load.
    What is going on?

    That's a good idea, but it was already set at the lowest resolution, so no luck, still freezes.
    The worst part is that when you open it in CS4, it does that weird layer grouping/clipping mask thing with the layers so you can't easily edit the file, if I save the file in the legacy version CS4 and open it in CS6, it retains the strange layer grouping. Although it does open it still doesnt solve my problem because now I just have a horrible to manage file.
    PS has anyone figured out how to fix the layer grouping issue with legacy (Cs4 and below) Illustrator files?

  • Transfer rate when moving larger files with MBP +AEBS over 802.11 n

    Hi Everyone
    I´m very confused about the capabilites of the new AEBS dual band.
    I have a Macbook Pro C2D 2,4ghz late 2007 running Snow Leopard , with an airport card N compatible.
    Recently i add to my home network an AEBS dual band , and i configure it in bridge mode , with support to the N and G nets.
    So when i try to copy a big file (around 2 GB) between the MBP and a FS mounted via NFS, sometime i have transfer rates about 9 to 12 MBytes / s , but after this al the copy´s that y do slow down to 3,4 MBytes / s.
    Also i test this copy operation with a 2,5" USB connected directly to the AEBS, and the results are the same , the max rate transfer is 3,4 MBytes /s.
    I tried with various radio modes , and different locations (Ireland, etc...) due to the limitation in Spain to use the 5ghz band.
    If i look the properties of the connection with de alt button it shows me that the MBP is connected to the N network at 5Ghz and 300 Mbits /s , but the transfers only reach 3,4 Mbytes /s. When i have a G net the transfers reach 2,4 Mbytes / s , i think that i have an limitation in my airport card or a misconfiguration in the AEBS.
    Sorry for my English.
    Thanks in advance.
    Nacho López.

    Hi Paul,
    The last test is....crazy.
    The environment (my home) are the next:
    AEBS dual band
    MBP connected via wifi N (5ghz)
    An old box with ubuntu server 8.10 (Pentium4) with a SATA drive
    External USB 2,5" connected directly to the old box via usb.
    I perform 2 test , a copy to the SATA drive of the old box, and another copy to the external USB mounted on the old box in the directory /opt/COMPARTIDO/usb.
    Here are the results of a scp :
    -----COPY TO THE MOUNTED USB-----------------
    batman-3:Movies Nacho$ scp -r Ironman\ P1\ \[1080p\]\[AC3\].avi [email protected]:/opt/COMPARTIDO/usb
    [email protected]'s password:
    [email protected]'s password:
    Ironman P1 [1080p][AC3].avi 100% 3334MB 19.6MB/s 02:50
    -------19.6MB/S TO MOVE 3,3GB OF DATA IN 02:50--------------
    -------COPY FROM MBP TO THE SATA DRIVE OF THE OLD BOX------------------
    batman-3:Movies Nacho$ scp -r Ironman\ P1\ \[1080p\]\[AC3\].avi [email protected]:/opt/COMPARTIDO/Mldonkey/incoming/directories
    [email protected]'s password:
    Ironman P1 [1080p][AC3].avi 100% 3334MB 15.7MB/s 03:33
    -------15.7MB/s------------------------------------------------------
    So definitly mi issue is not related to wifi N or the performance of my disks. I suspect that maybe the AEBS don´t manage well the protocols like SAMBA (the external usb drive was poor perfomance shared via AEBS) or NFS (the directory shared from the old box also has the same poor perfomance).
    If you can, try it, a simple unix scp can makes fly your files over your network.
    I´ll continue posting what if discover about this.
    Regards,
    Nacho.

  • Simple Math VI crashes LabVIEW 2009 SP1

    Hi,
    We previously filed a related issue, (ref #: 7302858). The last problem was resolved by 
    Andy Hertzka from NI re-compiled the VI and send it back to us. That re-compilation solved the LabVIEW crashing.
    However, the interesting crash happens again.
    I attached a working VI before the change and a non working VI after the change and save. All the change I applied to the VI is
    1. Add the "Word bits" as a connector on the diagram
    2. Save it Then the VI begin to crash LabVIEW 2009 SP1.
    Before the change, the VI was functioning all right.
    Any idea why this might be happening? Can you try to recompile the non_working version and send it back to me for a try?
    Thanks,
    Tian

    Tian,
    Like Andy I was unable to see why this code is unstable on your machine. I am able to run the code fine on my computer without any problems. Looking at the code on the block diagram I do not see any major "crash worthy" issues with it. 
    I have resaved the VIs like Andy had in order to fix your issue. By the way what OS are you using, windows 7? It might be helpful to save the log file for the LabVIEW crash. You should get this option when LabVIEW is restarted.

  • LabVIEW 2009 SP1 - Incorrect icon in connector pane palette

    In LabVIEW 2009 SP1 (I don't have 2010 yet to check it) there seems to be a minor bug in the connector pane palette.
    One of the connector patters appears twice, but when you select the second one, it shows up as the missing pattern.
    I'd post an image, but that function seems to be broken getting through my company's proxy server. So image attached (I hope).

  • Labview 2009 SP1 - Create exe option does not appear

    Hello everyone,
    I'm using Labview 2009 SP1 and I want to create a simple exe file (to run in the same computer that has labview or in any other  computer with the appropiate labview run time engine).
    I create a project with project explorer with the appropiate VI, everything OK for the moment, but when I right click on the menu "Build Specifications" of the project explorer I only have the options New and Help. If I click on New I only have "Source Distribution" and "Web Service (RESTful)" I would like to see the option Application and be able to create the EXE file.
    Anyone knows how can i create simple EXE files or make the option "Application" to be visible?
    Thanks for advance!
    Much thanks for your time and dedication!

    I guess you did not install the LabVIEW Application builder when you installed LabVIEW. When you do, it will allow you to create the exe and installer (You must be having a valid licence also).
    The best solution is the one you find it by yourself

  • Bridge CS3 now crashes when moving/copying files

    As the title says.
    A few days ago Bridge started freezing and I dumped the preference files from the user Library, the computer's Library and also the one in the "Save preferences" folder. Now it's giving me problems when moving/copying files with the 'Move to" and "Copy to" commands on the File menu. It works fine when I use one of the options on the "Recent Folders" list, but when I want to select a folder using the "Choose Folder" option, it just crashes.

    Hi Robert,
    I'm a developer from Br team. Thanks for reporting Br. problems.
    It seems like a memory issue. Please try this to help us identify the root cause:
    1. Disable all startup scripts (Edit->Preferences->Startup Scripts->Disable All), then restart Br.
    2. When Br is running, kill "SwitchBoard" process in task manager.
    3. When do Copy&Move operations, don't use Drag&Drop, try to use "Move To / Copy To" menu. (A known issue of Bridge, should be fixed in later versions)
    Does the crash still happens?
    Thanks very much!

  • Photoshop cs6 crashes when moving dialogs and windows

    So recently, Photoshop has started randomly crashing when moving dialogs around or onto 2nd monitor. The files I have open are not large, so I am looking to understand why this is happening. has anyone else experienced this with their application?
    Thanks

    It might be helpful if you'd go into your Windows Event Logs (specifically, the Application log) and look for the Error event indicating a Photoshop crash.  It may identify a module that will help narrow down the problem - though I suspect it will show a crash in the printer driver.  Copy the text and list it here.
