VLC still running in the background (~200% CPU)
Hello,
I noticed that my laptop was getting really hot so I checked the processes running. I found out that a VLC process was still running and using weirdly about 200% of the CPU... I couldn't kill it and had to restart. Any clue about how this could happen and how I can solve it?
To start it I just opened a video file, to kill it, alt+f4. Then maybe an hour later I found out it was still running. It is not the first time that this happens with VLC. If I remember well I had the same problem using Linux Mint 14. I'll try to see if in some way I can repeat the problem.

Just updated to 8 & now I can not open any web pages as well as firefox will not close out, it still running in the background after browser was closed. I uninstalled and reinstalled as well as disabled add-ons and plugins nothing has changed, can I downgrade back to on older version?

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Why does my iMac display keep shutting off? Computer still running in the background. I've tried unplugging and restarting, to no avail. The computer is well out of warranty - about 7-8 years old, running 10.6.8
Checked.... the settings had not been inadvertently changed, but I did move the scroll and reset them back to the original. Hasn't shut off again.... yet. Will re-post with follow-up one way or the other. Thanks.

LabVIEW closes while VI's are still running in the background
I have created a large application that is split between VB 6 and LV 6.1. The LabVIEW portion runs in the background, except that the VB portion can request that a LabVIEW user interface be presented on demand. Any time after this LabVIEW user interface has been opened and closed, opening and closing another application (or even just hiding a top-level window in another application) will cause LabVIEW to close, taking my background processing with it.
If the LabVIEW code is running as source code, LabVIEW prompts me before closing. However, when the LabVIEW code is running as an executable (.exe), the executable closes without prompting in this circumstance.
The scenario can be reproduced with a standard LabVIEW sample program. Proceed as follows:
1) Open VBToLV.vbp (the example program distributed with LabVIEW 6.1).
2) Start the VB program running.
3) Press the Launch LabVIEW button on the user interface of the VB program.
4) Enter an expression in the text box provided.
5) Select Display VI Front Panel.
6) Press the Run VI button.
7) Close the VI front panel by clicking its "X" button.
8) Open any handy application, such as Windows Explorer or Notepad.
9) Close this most-recently-opened program.
10) The LabVIEW Exit screen appears.
11) Exit LabVIEW.
12) Press the Run VI button.
13) An error occurs because LabVIEW has closed.
If the LabVIEW code had been built into an executable and called accordingly, there would have been no LabVIEW exit screen. The executable would have just exited silently.
This is not the way a COM server is supposed to behave. The VB program is still holding a valid reference to the server and it should remain open.
It appears that LabVIEW is monitoring the total number of top-level windows that are open. I suppose that this is how LabVIEW figures out when its own FP windows have been closed. In this case, it doesn't notice that all of its windows have been closed until some other window closes.
I have a work-around, but it's ugly.

Balance Technology Inc.Hi,
Perhaps you use references to windows in LabVIEW. If you get those
references with a full path (e.g. c:\code\subvis\vi1.vi), this will work
while in LabVIEW environment. But when an application is build, this will
fail, because the vi is no longer there. Try using the name in a string
instead (the OpenVIReference is polymorphic) with only the name of the vi in
it (e.g. vi1.vi).
There are some other isues that change when building an application. Most of
them are paths that change, and references that fail to open because of
them.
Regards,
Wiebe.

Labview 8.5 vi still running in the Background
I am using an old legacy system that is using Labview 8.5. When I shutdown labview, I get the message "Closing the project will abort some running VIs". My question is how do I see what VIs are running? It seems that I have an open reference somewhere, but I am having a really hard time tracking it down.
Basically, all VIs called are using the run VI node, so it is really hard to follow the code and see what is open at any given time. Any help would be appreciated. ThanksThe memory profiler (Tools -> Profile -> Performance and Memory) will list all the VIs in memory, which should give you a starting point to track down which one is still running.

MacOS X 10.5.8. I launch Firefox.No window opens. I thought my firewall was blocking it so it wouldn't show a window when online.I fixed this.Still no Firefox's display. I upgraded to Firefox 5. Same issue there. Ready to move to Chrome, fed up now. Can't find what's wrong nor where the key to solve this is hidden (code somewhere..). Thank you for any help//
this link you offered says: "can't find page"
Ninite, as it started "run", then got an error: An error occurred. The certificate authority is invalid or incorrect [0x80072f0d] ; ; 216
any other ideas ?
Any chance other browsers don't let me download Mozilla ? had if for years, went to update it, then uninstalled it, now neither Google Chrome or Internet Explorer will let me download it. Or maybe it is just my laptop, running on Windows 7 ? ? ? ? ? ? -
After I closed Firefox it seems to be still running in the background.
So it is said if I trie to open it again later. I have to restart the PC, to be able to open it up again. Then the system seems to close down Firefox before restarting.

Adobe Reader 11.
What's to do?
GreetingsSame exact same situation happened to me with Windows 8 64 bit, Adobe XI .
the CPOU is slowing down and is heated. the fans s running all the time. the only solution was for me to end the processes from the taks bars (one process per adobe file open !!!)
somethign is definitely wrong; but don't know if it is Windows 8 or Adobe; I thing it is Adobe issue. -
Is there a way to keep apps from running in the background?
I just updated to an Iphone 6, with the latest version of IOS. It's a great product, but for me there is one annoyance. There are times when my memory gets low. I find out that it's the apps that are running in the background. I personally don't use this. All it does is hog memory. Then, to close the apps, you have to close each one individually. I forgot how many apps I have open, I'm of the mindset that when I close the app, that it's "really" closed, not still running in the background. It would be nice if there was a way to disable this function. It doesn't seem to serve a purpose for me in the way I use the Iphone. I just "cleaned up my list of "behind the scenes apps" and I had about 20. It gets frustrating to have to go to each one to close it. Any comments or suggestions?
Some things that might help:
1. Only the most recently used apps actually occupy memory (used to be the most recent 4, but may have changed in the latest iPhones). After 4 (or so), IOS writes them out of active memory, as it does for even the latest 4 if there's no activity for a long time. So the business of closing all the open apps, apart from the most recent ones doesn't make a difference. Tis article has a good explanation:
http://www.speirs.org/blog/2012/1/2/misconceptions-about-ios-multitasking.html
2. There are settings about background app activity that might help:
- Settings, General, Background App Refresh controls which apps can update their data in the background
- Settings, Notifications controls which apps can tell you things, which they have to wake up to do.
- Settings, Privacy, Location Services controls which apps monitor your location - another activity that uses resources
Hope some of that helps -
Firefox is running in the background, but the process can't be ended using the task manager?
The program wouldn't open because it was apparently still running in the background, so I restarted a few times which didn't help. Then I tried using the task manager to end the process but that didn't work either. Then opened the command prompt and used taskkill, then pskill (using the PID number) but neither worked. The problem wasn't with how I was using these commands as they could close any other program I had running, just not firefox.exe*32. Any ideas?

Iphoto hogs my cpu, even when running in the background
Hi, I can't leave iPhoto running in the background because it regularly uses 47% to 98% of my cpu (although there are times that it only uses 12%). Eventually the computer heats up to over 200 degrees (F) and freezes, forcing a hard re-start. I did all of the iPhoto maintenance tasks (rebuilding, etc.). My library does have 3000 photos, but I am running 16 GB of RAM. I monitor the CPU use via "Activity Monitor" and no other program comes anywhere close to using that much CPU. I'd appreciate your suggestions.
This is iPhoto for iOS. You should post your question in the iPhoto for the Mac (iLife) forum to get better answers.

When making a call, sometimes, my iPhone 5 , gets stuck on 'Calling' than I have to press END..but still nothing happens, than when I press HOME button, the call app keeps running in the background and it keeps saying CALLING... than I have to wait 2 - 3 minutes and call again.
please helpHas nothing to do with the SIM or master reset. This has been done to my phone. The SIM once and the factory reset many times over. You all just sold us a bad piece of equipment and have us by the tail with our contracts so none of us can get a new phone without paying full price or re-upping our contract. I just got off the phone last night with your high up tech people (you know, the hidden number we get once we tear into your support people enough), they went into my phone again and still didn't find anything wrong. I about got fired from my job for not getting my calls and texts. The BBB has now been contacted, and I feel your end should shore this up for all of us!

I have firefox as my default browser. Anytime I click on an email or search for something, instead of opening my default browser, firefox loads a new firefox page. It is a blank page just as if I had never had one. It has nothing on it except how you would start out before you set up your tabs and history etc. My default firefox is still there running in the background but I must click on it and manually put in the link I was trying to open.
Any suggestions.Some added toolbar and anti-virus add-ons are known to cause
Firefox issues. '''Disable All of them.'''
Start '''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Firefox in Safe Mode]''' {web Link} by holding down the '''<Shift ''(Mac Options)'' >''' key, and then starting Firefox. Is the problem still there? -

Thanks for your reply.
Yes, I have waited for a while and the result doesn't change.
The Porblem here is the application is seen started in visual administrator.Only restart brings up the page back.
Can you please suggest anything.
Thanks and regards
