Unwanted Cursor Move Problem

Hello
I have a problem about cursors in XY Graph. I have two cursors and I want to get data between two cursors. I have snapped the cursors to the plot however, cursors perform unwanted move when I make them visible. hope there will be someone to help me.

You did not include any of your subVIs, but overall the code looks weird. Wy do you use a 1ms timeout to rattle through numerous property nodes of the same graph. That's a very nervous program. At least combine all thse property nodes into one and use a more reasonable timeout.
Can you attach a runnable version that includes all subVIs? Thanks!
We also cannot see the cursors because they are locked to a plot, but the plot has no data.

  • Cursor Movement Problems

    When I try to play certain games my cursor moves like a slow motion snail. I have Windows 7 and most games play fine. Can not seem to find a solution from game suppliers.

    Thanks BDAqua,
    I reached a senior advisor at Apple and we figured out that a program called TaskBoard was causing the problem.  Wish I had him on the phone last night.  45 minutes to not fix it last night versus 5 minutes tonight.  What was happeniong with the screen is not something that OSX could cause so he asked me to look at several programs and found it.  It is so good to have expertise available for customers.  Glad I switched to MAC after 27 years with Microsoft based machines.

    My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words and looks them up via dictionary. I currently have a wireless mouse connected and I am still having the same problems.
    I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
    HELP PLEASE
    Very worried!!

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
         after the chime press and hold down the OPTION key until the boot manager screen appears.
         Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

  • The timeline  and cursor move very jerky (in a continual chattery motion) in Windows 8.1

    in my project the timeline and/or the cursor move very jerky (in a continual chattery motion )  in windows 8.1
    i have set the Windows Software Compatibility setting for their "Window 7 emulator"  and the condition still persists.
    also the "fullscreen playback"  for the project used to  be very fine resolution and now it is very mushy...
    all  this tells me there are real problem with my Premier Element 10

    Littlefeather
    You are running Premiere Elements 10 on Windows 8.1 64 bit. The program works just fine in Windows 8.1 64 bit when run Windows 8.1.
    So do not go altering to another operating system. I know this first hand.
    The immediate factor that needs ruling in or out is your video card/graphics card. Specifically "Does your Windows 8.1 64 bit use
    a NVIDIA GeForce card? If so, that may be your answer. See Announcement at the top of this forum which describe the Premiere
    Elements 10 NVIDIA GeForce problem and gives the fix of how to roll back the card's driver version to get Premiere Elements 10
    to work for you.
    Once we are assured that you are not afflicted by Premiere Elements 10 NVIDIA GeForce syndrome and also know that your current
    video card/graphics card driver is up to date, then we can move on to seek other factors that may be causing the problem.
    For your convenience, the following is a copy/paste of the Announcement about the issue as it appears at the top of this forum.
    All the links and how tos that you will need are in this announcement.
    Premiere Elements 10 NVIDIA Video Card Driver Roll Back
    If you are a Premiere Elements 10 user whose Windows computer uses a NVIDIA GeForce video card and you are experiencing
    Premiere Elements 10 display and/or unexplained program behavior, then your first line of troubleshooting needs to be rolling
    back the video card driver version instead of assuring that it is up to date.
    Since October 2013 to the present, there have been a growing number of reports about display and unexplained workflow glitches
    specific to the Premiere Elements 10 user whose Windows computer has a NVIDIA GeForce video card. If this applies to you, then
    the “user to user” remedy is to roll back the NVIDIA GeForce video card driver as far as is necessary to get rid of the problems. The
    typical driver roll back has gone back as far as March – July 2013 in order to get a working Premiere Elements 10. Neither NVIDIA
    nor Adobe has taken any corrective action in this regard to date, and none is expected moving forward.
    Since October 2013, the following thread has tried to keep up with the Premiere Elements 10 NVIDIA reports
    http://forums.adobe.com/thread/1317675
    Older NVIDIA GeForce drivers can be found

    A February 2014 overview of the situation as well as how to use the older NVIDIA GeForce drivers for the driver roll back can be found

  • Macbook Pro 10.6.8 - Cursor moves by itself, types by itself, opens dashboard by itself, stops responding to keysto22000 there you go! Have switched out keyboards to no avail. Do not use wireless.

    Cursor moves by itself, types by itself, opens dashboard by itself, stops responding to keysto22000 - there be a good example. Seems to like the number 2. Have switched out keyboards to no avail. Do not use wireless. Does not start immediately upon turning on computer. Everything is okay from 10 to 20 minutes, then bang. Can deattach then attach keyboard and get a few moments of quiet. All this started today.

    If the same erratic behavior occurs when the external KB and mouse are completely disconnected, I think it's time for a Genius Bar appointment to have the problem diagnosed.
    http://www.apple.com/retail/geniusbar/
    You'll probably want to get the machine revved up ahead of time so it's misbehaving when you walk in the door, rather than count on it to act up — or not — after you and the Genius have been standing around waiting for a while. (BTW, I'm assuming that once it starts acting up, it continues to do so until you give up and shut it down. Is that true?)

  • Cursor moves on it's own on my 24" imac

    My cursor moves on it's own. I do not have a trackpad, or Timbuktu (not sure what that is?) I have used apple support on this once all ready. They had me do a restart from the system disk, run Disk Utility, unplug everything wait and then replug, zap the p-ram, dump a preference panel. But none of it fixed the problem. The cursor just shoots off to the side or the top or bottom depending on what it's closer to. I bought a new mouse, and still had the same problem, so I returned it. I upgraded to the latest OS, still have the problem. The problem continues when I'm working in Photoshop and Illustrator, which is really frustrating because it suddenly streaks across the page while I'm painting (in PS) or if I'm working an anchor point in Illustrator it suddenly pulls it off the page.
    Can anybody help me fix this once and for all?
    I really appreciate any and all suggestions.

    Restart the computer, as long as you're at it do a SMC reset:
    SMC RESET
    • Shut down the computer.
    • Unplug the computer's power cord and all peripherals.
    • Press and hold the power button for 5 seconds.
    • Release the power button.
    • Attach the computers power cable.
    • Press the power button to turn on the computer.
    PRAM RESET
    • Shut down the computer.
    • Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    • Turn on the computer.
    • Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • In large PDF files my cursor moves around the page at warp speed. It does not seem to make any difference if I slow it down with Sys Prefs. This is not only in preview but also other programs to open PDFs.

    In large PDF files the cursor moves at warp speed with a mind of it's own, I've tried slowing it down in Sys Pref with no luck. On small files cursor action is normal. This happens in Safari, Preview and other programs that use PDF files. Sorry to say this does not seem to be a new problem with 7.# I've had it with prvevious versions of operating system Right now I'm using a Apple wireless mouse and key board. Using the USB keyboard and mouse the same problem does not go away.

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • A small but very irritating bug in Mail: after pressing the spacebar after typing an apostrophe in a word such as "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.

    When composing an email in Mac Mail I've noticed a small but very irritating bug: pressing the spacebar after typing an apostrophe in a word, e.g. "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.
    Any ideas?

    I just recreated this problem on my iMac (wired KB, no wireless KB) by changing Mail > Preferences > Composing > Spellcheck from "as I type" to "never". Then type a contraction ending in 're and the space bar causes the cursor to jump back as others have stated, to the spot 'r|e
    Next, I went into System Preferences > Keyboard > Text, and turned off "use smart quotes" and the problem went away again.
    From this point (smart quotes off, spell checking never), if I turn Smart Quotes ON, the problem returns.
    The problem is dependent on the state of both settings.
    The spacebar in Mail "works" if I have either of the following setting combinations:
    Keyboard: smart quotes OFF, Mail: check spelling ANY SETTING
    Keyboard: smart quotes ON, Mail: check spelling AS I TYPE
    Other combinations FAIL
    Keyboard: smart quotes ON, Mail: Check spelling NEVER
    Keyboard: smart quotes ON, Mail: Check Spelling WHEN I CLICK SEND
    Looks to me like there's a bug in Mail > Preferences > Check spelling > NEVER and WHEN I CLICK SEND that interacts badly with Keyboard > Smart quotes ON.
    Thanks.

  • Why does the mouse cursor move to away from the currrent application without the mouse being moved

    the mouse cursor moves away from the current application without the mouse having been moved - this started with the new version - re-installing Firefox makes the problem go away for a short period - re-installing is not a solution
    == This happened ==
    Every time Firefox opened
    == a few days after installing 3.6.3

    Hello Jim.
    It's probably one of three things:
    #your mouse is getting old (this behavior is common in old optical mouses);
    #you have software that is making your mouse cursor behave unexpectedly (I know of an option in Windows that will automatically move your mouse to windows buttons...);
    #or you may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

  • Jumping mouse cursor movement with secondary monitor

    Mouse cursor movement is interrrupted or jumps as soon as a secondary monitor is connected to my iMac. Either mouse movement direction is affected. Typically cursor movement stops for about a second while moving mouse further. Then suddenly cusor jumps either forward or backward.
    As soon as secondary monitor is dicsonnected, cursor movement is perfeclty in synch with actual mouse movement.
    I would very much appreciate any hints to solve this issue.

  • How to avoid built-up for "cursor move" events?

    I have a rather complicated program where several graphs need to be interactively updated according to cursors using "cursor move" events. The problem is that the recalculation is relatively slow and the behavior is less than satisfactory. Since the cursor position needs to be "tweaked" until the result is as desired, I cannot recalculate only at the "Cursor Release" event.
    Lock front panel=enabled makes cursor movements tedious because the cursor movements is very
    jumpy and non-interactive. Not user friendly!
    Lock front panel=disabled queues up way too many move events and once the cursor is released
    the graph continues to jump and recalculate for ages.
    The attached demo (LabVIEW 8.20) shows one solution attempt that actually works pretty well: Skip the recalculation unless the cursor position from the event terminal is equal to the cursor position of the graph property node. This basically races through all unecessary intermediary recalculations on stale positions. However, the code can get complicated very quickly if there are multiple cursors.
    In my opinion, cursor move events should not get queued up! The event buffer should hold only exactly one entry:
    the most recent cursor position for each cursor. Can anyone think of a scenario where the extra cursor position trail is useful? The positions are pretty random anyway, right?
    Does anyone have other (better!) ideas how to work around this problem? I definitely want to keep it simple and not throw lots of code at it.
    The attached demo contains more details. It demonstrates the problem if "selective updates" is checked. If unchecked, it implements the above mentioned workaround.

    Thanks for the example.
    The more I think about this, I strongly prefer my original method. It uses minimal code compare to the other solutions offered here. As a demo, I am attaching an implementation to a slide control.
    Fo those without LabVIEW 8.20.
    All slide events have "lock front panel" disabled.
    TIme delay is 500ms, simulating some complex calculation.
    As you can see, it works extremely well:
    NO shift registers, extra loops, queues, tuning parameters (min times, etc.), etc.etc.
    Just a deceptively simple "equal" followed by a case structure.
    The demo shows a typical recording if I quicky move the slide up and down, then release it. You can see that the raw event structure takes more than 40 seconds to stabilize while my selective solution follows the slider position almost perfectly despite the 500ms stall in each update.
    See for yourself! Can anyone think of a drawback of this method? Even if the slide terminal is not in the same loop, a comparison of a local variable with the newval should do the trick just fine.

  • Keyboard issue - Cursor moves backwards while typing

    Hello,
    I have an issue with the keyboard of a Macbook Pro (2011). When I'm typing (email, notes or word etc.), the cursor moves up a couple of lines by itself and I end up typing in a middle of another word. It seems to do so randomly. I have done what apple advises in case of keyboard issue but it hasn't solved the problem so I was wondering if any of you had any suggestion on how to solve that. Thanks

    If you have another keyboard, use it see if the problem crops up there. 
    Reset the SMC:  http://support.apple.com/kb/HT3964 Intel-based Macs: Resetting the System Management Controller (SMC)
    From the disc that originally came w/your comp, run the Hardware Test & post the results.
    Keyboard may be dirty.  Try cleaning it using an air compressor and/or a brush vacuum hose.

    I figured it out. Thanks everyone!
    I had to turn on my wireless mouse... And even though I wasn't using my wireless mouse and just the trackpad...I had to turn on my wireless mouse then adjust those settings...Had to turn down the speed. Then Once I shut the mouse off and started to use the trackpad again it works perfectly.
