Missing Mouse Up Bug

I have Labview 6.02. Sometimes when my VI is running, Labview misses
'mouse Button Up' events. So if I try to scroll, I can't let go of
the bar. Or a button will get stuck down. It usually catches the
'mouse Button up' about 5-10 seconds later. This make it really
difficult to use!
Anyone else seen this? Any solution?

>Nothing is using any significant amount of CPU.
How is the actual CPU usage when the program is running?
I have written an application that sometimes receives spikes of up to 600 UDP packets/second (several ports). Its running on an old 133MHz Pentium and there is no slowdown at all.
How are you using the ethernet. UDP or TCP? For TCP, do you maintain a connection, or establish a new connection for each chunk of data? Do you use datasocket connections or plain TCP?
If using Windows, go to a command prompt and type "netstat -an" after runing the program for a while. Is there a buildup of many stale connections.
Of course it could also be a hardware conflict, e.g. between the drivers for the NIC and the video card. Have you upda
ted the network card drivers? Maybe try a different NIC or put it in a different PCI slot.

  • Missing features and bugs in 2.2 update...

    Missing features and bugs in 2.2 update...
    Here is my shortlist:
    1. Copy/Cut and paste - sadly still missing...
    2. Landscape view for keyboard - SMS and Email - still missing...!
    3. AM/PM indicator missing from "unlock" screen (in 12 hour clock) - BUG
    ... What's wrong with Apple these days - all of these issues (listed above) could have been easily implemented in version 2.2 and were frequently requested by all iPhone users since version 1.0 and yet Apple have ignored all of them...

    These features may or may not be that difficult to include, but what made you "fork out huge amounts to pay for a 'top of the range' iPhone" in the first place?
    As already provided, Apple has what is called their own "allocation of resources and prioritization", and if what is included doesn't meet your needs or wants, you should not have purchased an iPhone in the first place, or continue to keep using the iPhone if Apple doesn't include the features you need or want in a time table that meets your expectations, since there are plenty of cheap $100 phones that meet your needs or wants, you have a wide range of other phones to choose from which are less expensive, so that is exactly what you should do. No point in continuing to use a device that does not meet your needs or wants. Use one of the many less expensive devices you have to choose from that meets your needs or wants and move on.

  • Missing Mouse Events

    I’ve noticed that it is possible to miss mouse events
    if you move the mouse very quickly. For example, if you quickly
    move the mouse off a control, you can fairly easily miss the
    MouseOut event. Is there a Best Practice way to get around this?
    Thanks!!

    If you move your mouse quickly over an object, you can fairly
    easily miss the mouseout event. This is especially true if the
    object you are moving the mouse over is fairly small.

  • Combo Box Indicator: mouse wheel bug or feature?

    Both ring indicator and slide indicator works fine even when the mouse wheel property is enabled.
    But user can change value of the Combo Box indicator at runtime.
    Shouldn't it be disabled, by default, just like for the keyboard?  After all, it's an indicator.
    I know I can disable the mouse wheel feature.  It should be disable by default.
    Or is there any use of this feature?

    Mouse Wheel bug.vi ‏12 KB

    I think what you are seeing is a minor bug introduced by the lack of a "Combo Box Indicator" on the palattes.  You must drop a control then change direction and there appears to be no built in mouse support property written on direction change leaving you with the default mouse wheel support for a control.  Since this is a "windows only" property there might not be an easy way to write the property on direction change without querying App.OS target.  And then what do you do on targets that do not have support for the property?  Change the behavior?  THAT would confuse just about everyone who works with multiple OS's
    The work arounds:
    Use the key navigation page and pay attention to mouse wheel support for indicators
    Add your own combo box indicator to the controls palatte with the right mouse wheel support
    Write a VI Analizer test for "Indicator with mouse wheel support"
    In Short;  this seems like one more thing that can easily trip up a developer.  A VI Analizer test for this could help save us from ourselves.  Consider uploading yours to the VIA Enthusiasts group

  • Mac mini and mouse: Curious bug

    My Mac mini shows a quite curious bug. When I move the mouse while logging off an user - whether an admin or one with restricted rights - the mouse freezes. I have to log in and off again to make the mouse move again. I changed the mouses and re-installed the OS. It didn't fix the bug. Has anyone an idea how to solve this problem?

    Hi there,
    I am also having bizarre freezes of the mouse (wireless USB Microsoft (yuk) which had been fine. The mini, however, has been weird anyway lately. I had to "zap" P RAM something not done since golden days ) to get the external firewire drive to mount again...I am now running a 7 port hub(firewire and Usb) (iogear) and all is working well . Mouse , however is plugged right into the USB port on Mac Mini . It also seems to not be playing well with Firefox version 2 (disn't do the FF 3 update yet because I was already having problems)...
    I'd say I'm getting mouse freezes every time I leave the computer for more than 10 minutes. There seems to be some relationship with "sleep' too...running 10.4.11 and have it set NOT to sleep because of this, but it does anyway and then freezes and won't wake up (after left on for a while). I have run all the utilities including Onyx & they say all systems GO.. I do plan to work on it via Disk Warrior by connecting it to the G5...
    Any ideas? I use a satellite ISP...This started to happen about a month ago...all of this sleep, freeze, missing port behavior...I have a lot of plugins for firefox as I'm an active twitterer (using TWhirl). so there are a bunch of new apps and online apps I'm beta testing too...there may be something here !
    Thanks so much.
    best to y'all

  • Missing mouse indicator

    Hi,
    I have a small yet sometimes annoying problem.
    When I want to rename a file or folder in Thunar (I'm using xfce) I don't have a mouse indicator. I don't know if it's actually missing or if it is just white because at some letters a white pixel appears.
    In Firefox this problem doesn't occur and I have the black flashing indicator in every form field.
    I looked through my applications and noticed the missing cursor in the search field of geany or the typing field in gajim, too
    I already tried different cursor themes and also gtk themes.
    Anyone has an idea how to solve this?
    Thanks in advance.

  • Firefox missing mouse clicks

    I have updated both my desktop (Win7) and my laptop (WinXP) to Firefox 9.0.1 (from 8.0) and both are suffering from this issue.
    about 99% of my left mouse clicks seem to get ignored, but middle and right are both perfectly find. Left button operates correctly in all other programs.
    The mouse works correctly in the taskbar/menus/tab bar/scroll bar, but stops as soon as I am inside the page display area.
    Sometimes if I click continuously for 10 seconds I get an ok click, or sometimes I have to use a different program for a minute and then come back, then I can get 1 or 2 clicks before it stops working.
    Currently navigating using tab, and shift+tab.
    This is very very annoying, has anyone else noticed this after update? or have any ideas?

    My current issue is that if the simulator is frozen (system time is cycling within a 100ms window) mouse clicks on buttons are getting lost.OK that's an entirely different kettle of fish. Firing an action does require that the mouseReleased be later than the mousePressed, and that both be over the button.
    Consider ths scenarion in any normal application that doesn't interfere with the system time. The user presses the mouse over some other component, drags over to the button and releases it. Next, the user presses the mouse over the button, drags off the button and then releases it. This isn't supposed to trigger the button's ActionListener#actionPerformed.
    With the system time looping, how does the runtime know that this isn't the case?
    I can see the button border change when I move the mouse over the button,that's rollover, triggered from mouseEntered. timing is not an issue.
    but the mouse click is lost (button does not get depressed).See above.
    Sometimes it works fine for a few mouse clicks and other times several mouse clicks will be lost in a row.See above.
    It seems random.In a way, it is.
    This seems to be more prevalent with buttons than capturing a mouse click on a panel where I do 2D drawing. Not sure why.Could be just human susceptibility to guesswork, or may actually have something to do with the occasional additional processor cycles involved in the custom painting. Since you haven't described the frequency of repainting nor its complexity, that guess is my susceptibility to guesswork ;)
    When I put the simulator into Run mode, it works perfectly, never missing a click.Of course it will.
    Anyone out there have any insights into what might be going on under the hood inside Java/Swing with mouse events and the system clock?See above.

  • Mountain Lion Missing Report Safari Bugs Menu Item?

    I recall a Bug reporting menu option in Safari which seems to have disappeared in the latest version in Mountain Lion. Or am I missing it?
    Perhaps the Apple folks think Safari is now perfect. ;-)
    I was trying to view photos of this Hilton
    http://www.hiltongrandvacations.com/Resorts.aspx#details/index&resortId=93&backF unctionality=0
    by clicking the More Photos button, but clicking on Next arrow kept giving an error:
    Could not extract width/height from image: http://multimedia.hiltongrandvacations.com/ws/ResortGallery/dynamicImage.cfm?id= 606&width=880&height=530. Traced measures: width:0px, height: 0px.
    though the site and photos worked fine when I tried it in FireFox, etc. But, I could not find a way to report it to Apple from within SadFarI.
    Is the Report button hidden somewhere in some other menu? Thanks.

  • Mouse click bugged

    Hello.
    I've spent a few days now troubleshooting this problem but I guess I'll have to refer it to the boards, I'm utterly stumped.
    My mouse clicking has started cutting out intermittently.
    The Symptoms are these:
    When in an application such as safari, my left or right click (using a mighty mouse) will be ignored for long periods of time, or only be registered after 50 or so clicks have been made. The mouse still tracks fine and I can often click UI elements or links within the page but can't click the main menu or some of the other UI elements. I also can't click into another application to change the frontmost application.
    However, at all times I'm able to click on the finder in the background and drag around folders and whatnot.
    First of all I presumed it was simply a case of Safari, Text Edit, iChat etc not being the frontmost application. However the menus at the top always showed the correct application as being active and never displayed the UI elements as faded as would be the case with an application which is not at the front.
    Sometimes switching too and from the application window will restore click sensitivity, relaunching the finder also works. However the clicking bug will return only a few seconds later.
    Things it's not:
    1) It's not a universal access problem. Made sure this wasn't active
    2) It's not a fault with the Mighty Mouse. I checked it on other computers, works fine.
    3) The mouse hasn't been incorrectly configured in System Preferences.
    So basically the situation I'm in now is that any application will spontaneously lose mouse clicks as if some phantom application was running in the foreground absorbing them. The only exception to this rule is the Finder which works at all times (but from which I can't select other windows to bring other applications to the foreground) and who's quitting will reset the bug temporarily.
    No other applications are running, my knowledge of the process IDs for various system level processes is poor but I'd be able to notice anything than totally out of place applications running in Activity Monitor.
    Some UI elements are unaffected by the bug, such as finder panes and scrollbars, others are such as title bars, traffic lights and control buttons.
    I'm at my wits end, in over 15 years of using Macs this is by far the most annoying bug I've ever come across (thankfully I've not had many others to speak of) and one which I'm completely baffled by.
    Oh and the latest security update is installed.
    (right now in fact, I just went to go click on the apple menu from here in Safari and it won't register my clicks, none of them - I had to tab out to the finder to click the apple menu)
    Dual 2ghz G5   Mac OS X (10.4.6)   2.5 GB ram

    Yup, thanks.
    I had to use the preferences to work out what the problem was - I had a hunch because safari was opening any link I clicked in a new tab so I set the middle button to open spotlight. Sure enough, every click I performed with the mouse triggered spotlight.
    All I did was deactivate the middle button action and I could get a single left-click working fine. However, since the Mighty Mouse interprets Right Mouse + Scroll Ball as Middle Click, I'm left without a right click.

  • Mouse drag bug since update

    I have already filed a bug at apple for this.
    With me, several other have this same problem (see http://gathering.tweakers.net/forum/list_message/34648240#34648240 )
    Since the update of I think 2 weeks ago now, I sometimes have problems with something that looks like a mouse draglock. It is not hardware related, since the issue is gone when rebooting, and it's reproducable on both external mouses and internal trackpads.
    To reproduce:
    mouse your cursor
    while the cursor is moving, click or tap
    the mouse is now in a draglock state.
    you can get out of this state by repeating the actions above.

    I have what appears to be the same issue.
    I cannot get the mouse out of draglock state and I need to restart for it to go away.
    Please help Apple!

  • Webvpn install svc *.pkg missing after reload - bug ?

    Hello !
    I'm using a CISCO1921/K9 with IOS 15.1(3)T1 and licensed fetaures ipbasek9, securityk9, datak9, SSL_VPN.
    After a working setup of webvpn I'm running in troubles after a reload - of course, the running-config is copied before reload ; )
    This config line:
         webvpn install svc usbflash0:/webvpn/anyconnect-win-2.5.3055-k9.pkg sequence 1
    is missing after a reload. Consequence: the "Anyconnect Client" refuses to connect. What can be the reason? Is it the sequence "1" - I only have one sequence and not more of them? I use this CLI input
    webvpn install svc flash:/anyconnect-win-2.5.3055-k9.pkg sequence 1
    to install - the line above appears in the running-config output - is this the right way?
    Thankfull for hints,
    Grüße

  • Detecting missing mouse clicks?

    There are some times when a user clicks on a movie clip in my
    SWF that the mouse click goes undetected by any of my mouse event
    handlers.
    I even added a MouseClick listener at the root sprite of my
    SWF.
    Is there any way to detect where this mouse click is going,
    and why it is not being detected by anything?
    NOTE: I have *only* seen this happen so far when a user
    clicks on a movie clip that I have dynamically loaded. The movie
    clip is not playing, and I am manually calling gotoAndStop() on the
    movie clip various times. Not sure if that is related.

    please don't cross post.

  • Missing Mouse with new MP

    Has anyone else received there MP with a keyboard and no mouse?
    Not that I am a fan of the mini mouse but shouldn't it be in the top packaging or under the keyboard?
    Guess it's time to call apple care. Other wise the system is amazingly quite and fast!

    Yeah its in your software disk box lol<</div>
    Doug I didn't read your post until a week after getting a new one sent to me.
    You'd think apple service would've known and have me look there. Who reads the manual anyway? 2x LOL now I have two for one.

  • Missing mouse clicks

    I have no idea why, but some mouseclicks are missing here. I can click stuff, but it doesn't do anything. This is maybe every 10th click. Any idea why this happens?
    Thanks

    For example double clicking in Finder to open an application, clicking a link in safari, clicking on a window... everything...
