Delayed Keyboard Response

I am using a Logitech K750 Solar Powered Wireless Keyboard which uses a USB transmitter not Bluetooth. I am using it with a late 2009 iMac with 8GB of Ram and OSX Mavericks.
It wasn't always this way but for some time now, when I type I occasionaly get a delayed response to my keystrokes, including the dreaded "spinning beachball." It takes a second or two for the display to catch up to my input (I don't type THAT fast!) and this is quite annoying and disturbs my workflow.
Originally I thought it was the Logitech keyboard that was the problem, but eventually they told me to try the original bluetooth wireless keyboard that came with the iMac to see if it happened with that too. IT DID!
So Logitech is off the hook.
Does anyone have any idea what might be causing this problem? I have 8GB of memory and tons of hard drive space, so I doubt either of those are an issue.
Does anyone think it could be a wireless issue and if I got a USB chorded keyboard the problem would disappear? I guess I will have to try that but since the bluetooth keyboard came with the iMac, it should work even though its wireless.
If anyone has an idea here, I'd love to hear it.
Thanks.

Hello Jeff Friedman,
I'd suggest resetting your system's PRAM.

TP Yoga 15 - Windows: Keyboard response too slow after coming back from hibernation

I've got the same issue as outlined in this thread for a Y50 - there seems to be a BIOS update to solve it, but what about TP Yoga 15? Quote:Simply put, In keyboard properties , the Repeat delay is default at maximum (eg, holding down a keyboard button and how fast it generates the key strokes). When the system is put in hiberanation, then turned on again to come back, the Repeat delay some how gets decreased to about 2/3 of what it originally is. https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Re-Y50-Windows-8-Keyboard-response-too-slow-after-coming-back/td-p/1676309/page/1

hi guys,
Can you please provide also these additional information:
(this is to check if the issue is isolated to a certain model number)
Model Number (eg. 59-xxxxxx):
Place of Purchase (eg. Amazon, Bestbuy, etc.):
In addition, the solution from this thread seems to be a good workaround (the app is for Win7 but may also work for Win8.1)

JTextField: How to modify keybinding / keyboard response?

Hello Experts,
For a certain programming purpose, is there a way to modify keyboard response?
I have created a JTextField txtSample. When it gets the focus, I want it to behave as following:
1. When user presses '+' key, instead of printing '+' in the text field, I want to do some actions and the '+' is not printed.
2. When user presses 'a' key, instead of printing 'a' in the text field, I want 'o' to be printed.
I have done the following for the first purpose, but it doesn't work:
Action addTrans = new AbstractAction() {
     public void actionPerformed(ActionEvent e){
          System.out.println("User has pressed + keypad");
txtSample.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_PLUS, 0), "addTrans");
txtSample.getActionMap().put("addTrans", addTrans);Any advice would be greatly appreciated.

camickr,
First amazing thing, the first time I clicked on the link
Works fine is this example:
http://forums.sun.com/thread.jspa?forumID=57&threadID=622030 it gave an error message.
Second amazing thing, I checked on the API of KeyStroke
getKeyStroke
public static KeyStroke getKeyStroke(char keyChar)
    Returns a shared instance of a KeyStroke that represents a KEY_TYPED event for the specified character.
    Parameters:
        keyChar - the character value for a keyboard key
    Returns:
        a KeyStroke object for that key
getKeyStroke
public static KeyStroke getKeyStroke(int keyCode,
                                     int modifiers)
    Returns a shared instance of a KeyStroke, given a numeric key code and a set of modifiers. The returned KeyStroke will correspond to a key press.
    The "virtual key" constants defined in java.awt.event.KeyEvent can be used to specify the key code. For example:
        * java.awt.event.KeyEvent.VK_ENTER
        * java.awt.event.KeyEvent.VK_TAB
        * java.awt.event.KeyEvent.VK_SPACE
    The modifiers consist of any combination of:
        * java.awt.event.InputEvent.SHIFT_DOWN_MASK
        * java.awt.event.InputEvent.CTRL_DOWN_MASK
        * java.awt.event.InputEvent.META_DOWN_MASK
        * java.awt.event.InputEvent.ALT_DOWN_MASK
        * java.awt.event.InputEvent.ALT_GRAPH_DOWN_MASK
    The old modifiers
        * java.awt.event.InputEvent.SHIFT_MASK
        * java.awt.event.InputEvent.CTRL_MASK
        * java.awt.event.InputEvent.META_MASK
        * java.awt.event.InputEvent.ALT_MASK
        * java.awt.event.InputEvent.ALT_GRAPH_MASK
    also can be used, but they are mapped to _DOWN_ modifiers. Since these numbers are all different powers of two, any combination of them is an integer in which each bit represents a different modifier key. Use 0 to specify no modifiers.
    Parameters:
        keyCode - an int specifying the numeric code for a keyboard key
        modifiers - a bitwise-ored combination of any modifiers
    Returns:
        a KeyStroke object for that key
    See Also:
        KeyEvent, InputEventThere is no indication that one method consume the keystroke, while the other does not. Now, I understand that keybinding can prevent the key from reaching the model.
And last, yes, you are right. It would be better to use DocumentFilter to serve
When user presses 'a' key, instead of printing 'a' in the text field, I want 'o' to be printed.Thanks for all your effort to guide me and sorry for the misunderstanding,
Patrick

No Response - Severe Delay in Response

I don't know what happened since I added no new hardware or software but one day it was all working fine the next I started having severe problems.
I did a repair installation and it didn't work so I completely uninstalled and then re-installed (after a reboot) and it still is acting up.
None of my other software, Adobe or otherwise, is acting strangely, only Premiere. I'm open to any suggestion because this is really freaking me out.
I was capturing SD footage via a Canon XL1s and having no problems. After about half of the tapes were done I quit for the night. The next morning when I went to start capturing again, Premiere locked up after opening the capture window. I tried a second camera (a Sony HDR-HC9) but had the same problems. I swapped out data cables, same problem.
Then I noticed that playback controls of the video already on the timeline had severe delays, up to 3 minutes, before responding to "play" and "stop/pause". I also noticed similar long delays when selecting windows within the project and even in the pulldown menus.
I deleted the current project and created a new one but the problems persisted. I opened old projects that I KNOW are good, but the problem persisted in these as well.
When I close out Premiere the "Adobe Premiere Pro.exe" process stays active in the task manager for up to 5 minutes after I closed the program.
Other then the minutes long delays in response, if I wait for it, the software seems to operate properly but will often just lock up and I have to do an "End Program" to get out of the lock up.
As I mentioned, I have completely uninstalled and reinstalled the software and none of my other software seems to be affected. WTF!
Alienware Desktop PC
Dual 2.8 Ghz Pentiums
2G RAM
WinXP w/SP3
PPro CS3 (part of Premium Production Package)

You can try resetting the preference file to the defaults by holding
down the shift key while you start Premiere and keeping it held down
till the splash screen displays.

Huge latency / keyboard-response-time when typing in IDE

I am experiencing a huge latency when working with some IDE's text editors, and keyboard response time is annoying long, sometimes what I have typed appears after a whole word is typed.
This happens in some IDE's which do some background parsing as I type,
hard drive led turns on before the text editor shows what I have typed which makes me suspect it has something to do with spin down (which yet doesn't make much sense)
any idea guys?

I don't know which IDE you are using, but one which huge IO on background parsing sounds for me like Intellij IDEA :-)
There was a bug with java 7 which makes the entire text editor really slow.
http://youtrack.jetbrains.net/issue/IDEA-73128
But this is fixed with the release 10.5.2 which was released this week. In this case you should install the update, otherwise no idea.
Maybe you should post which IDE's you are using so the people here must not guess to help you.

Slow Keyboard Response

I'm developing applications in flex and notice there is a
slow response from text input boxes that sometimes miss keystrokes.
This is particularly noticeable in login entry forms where keying
in username / password which is normally done very rapidly, will
often miss key strokes.
I've tried upping the frameRate to 60 in the application,
however this does not seem to improve the situation.
I'm just starting to develop a new web content application
that will require lots of keying, and this response issue will kill
the usability.
Cheers,
ap

Vygo,
Are you experiencing the problem on a Vista Machine? I was
suspicious that it's a potential problem with Vista and not so much
Flex.
On google I found others who had reported keyboard response
issues with Vista. I did a regedit patch but that has not solved my
problem.
I'll do some more testing on one of XP machines and make
sure.

Keyboard response chang in iOS 8.0.2 for anyone else?

Keyboard response chang in iOS 8.0.2 for anyone else?

Other people have reported issues with the keyboard in iOS 8. I had some problems and I reset all settings and that fixed most of the issues - everywhere but in this forum. But the keyboard problems in this forum are a as a result of the crappy software that this forum runs on.
First reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up. See if that does any good.
If that made no difference, try this. Reset all settings. You will not lose any data, but most of the device settings will have to be entered in the settings app again. Settings>General>Reset>Reset all Settings.

Slow keyboard response, lagging

Hello - ever since the upgrade was pushed down to my GS3 my keyboard response has been very slow. It is very noticeable when I go to type in a URL, or do a search. It also is pretty slow when I go to start to text. It just doesn't type real time like it always has. Is anyone aware of this issue? Any help on troubleshooting would be appreciated. Thank you.

caflirt22:
Give this a try.....
menu > settings > application manager > swype over to all > .. then scroll down to Samsung keyboard & select it - then press > clear Cache / clear Data
It seems to work great so far. I just did it but we'll see. After my upgrade it seems to have kept the old keyboard or data has piled up just slowing the application down. Once I cleared the data the keyboard look changed but seems to work a lot better.

Delayed Keyboard/touchpad response when waking up.

in the last couple weeks, my power book has been acting kind of weird... When my powerbook is woken from sleep, the keyboard and touchpad take about 20 secs before they respond... the applications and stuff all do there thing, but there is no input for about 20 sec...
any ideas? this has only just sprrung up.. i'm wondering if it was an update or soemthing...
UPDATE: It looks like this problem only shows up when the lid is closed, then opened.. if i put it to sleep when from the system menu it works find when it wakes up.

I've the same problem with my iBook G4... I have Tiger installed.
Prior to Tiger my baby never fail on me... I feel so disappointed with my baby.
So far this issue still haven't solve...
...HELP!!!

Keyboard Response Problem

Hey All
I have a 2010 Macbook Pro 2.4IntelCore 2 Duo 4GB Ram and a third party 500gb Hybrid HD.
I pruchased the mac used and it has worked well for the most part, save for the keyboard. Here is the issue.
First, the left shift key never worked. Sometimes the ikcomma arrows wouldn't work but not often. It reset everything according to many of the instructions here. To no avail. So I figured it was a hardware problem. I saved up and bought a new keyboard, installed it and it didn't fx anythng.
Now, the key responses are getting worse and worse. I can shut down the computer and ket the key to work occasionally, as you are seeing with my typing. But it takes at least 20 minutes of the mac sitting for the keys to register at all now. If i tap them repeatedly, it makes no difference.
So I am at a loss. I have reset everything software/SMC/etc multiple times, I've replaced the keyboard with new stuff, and it has never been dropped, gotten water damage, anything.
What else could be causing this problem? this morning the arrow keys stopped responding, so the problem is spreading... My job requires immense amounts of typing, so I can't be caught without a keyboard for a few days. Trying to get it diagnosed now, because it is spreading...
Any suggestions are much appreciated.
Austin

I am not surprised at the unfavorable results regarding the Pram reset and OS installation. From my perspective that tends to support my thesis that your MBP was defective when you got it. The fact that the external keyboard works tends to confirm that.
The only solution is to replace the MBP keyboard, which is a fairly complex endeavor in a Unibody MBP. You may look at iFixit.com for pricing and instructions for what is involved (do it yourself). To have Apple do it probably is not cost effective.
Often a liquid spill is the cause of such a problem. I hope that for your sake the difficulties are confined to the keyboard and do not migrate to other parts of the MBP.
Ciao.

CallableStatement performance delay during response

I've Oracle 8.1.6, and Java server with connection pool of 50 JDBC connections.
For each external request Java server calls one PLSQL procedure through CallableStatement.
During performance test I'm constantly pumping requests to server from 50 concurrent threads and logging response time measured around CallableStatement.executre() method.
Result in strange, I can see clear cyclical pattern: ~250 requests completed with ave. response time 30 ms, next ~250 requests competed with ave. response time ~300 ms. Next ~250 - 30 ms, next ~250 - 300 ms. and so on many times.
In attempt to explain periodic delays I added code to capture timestamps in PLSQL procedure (I had to create Java Stored Procedure for that) and I added 2 out parameters to return timestamps to Java.
Now I logged following timestamps:
A - in Java server just before CallableStatement.execute()
B - in oracle at very beginning of PLSQL procedure
C - in oracle at very end of PLSQL procedure
D - in Java server just after CallableStatement.execute()
New test shown that
a) pattern still same - my extra JSP calls didn't changed whole picture.
b) SURPRISE :
time to "send" request (B-A) is always about 5 ms.
time in PLSQL (C-B) is more or less flat and is about Long postings are being truncated to ~1 kB at this time.

I'm not sure what do you mean by "traced SQL" or how to look for wait events (I'm no good at Oracle internals, YET). If you can tell me specifically what to do I will be gratefull.
We have DBAs here and I talk to one of them. He told me without even checking database that it is warking fine :(. And proposed to run snoop when he will have time. Since I have no rights myself I'm waiting. After that I hope I will know is it JDBC driver or database.
As for JDBC version I tried latest ojdbc14.jar, classes12.zip both thin and oci8. No noticable difference.
And thanks for reply

HELP: Delay HTTP Response

Hi,
I'm trying to use a simple HTTP Servlet to provide a synchronous interface to an inheritantly asynchronous systems.
For example
1. Client does HTTP POST
2. Servlet receives request (via doPost)
3. Servlet generates an internal asynchronous request
4. Servlet receives an internal asynchronous response
5. Servlet returns the HTTP response
6. Client receives the HTTP response
How can I get my servlet to delay sending the HTTP response once I've exited the doPost() method (or is there a more clever way to do this?
Thanks.
Chris

You can't. But you could control when you leave doPost() by sleeping for the requisite amount of time.
Of course you can't control what the network of processes between your servlet and the client does or how long it takes, but I suppose you have taken care of that in some way.

Wireless keyboard response issues

Hi,
Has anyone else had a problem with the keyboard not being responsive while typing? It is an intermittent problem which I thought might be the batteries needing replacing but it still happens with the replacements. Any advice most welcome.
Ta
Moxx

where is your wireless receiver is located
for me find this is better to have it on the above somewhere on the desk and if you have like a usb cable with a usb plug on a stand like. a picture is shown
this would be a handy thing to have on your desk on the surface and it will help the signal with less interference and i have my reciever above my desk and it has worked for me better
Please provide Kudos to whom has provided answers or
good points or advice..

3 questions: Shake 2 shuffle; keyboard "response" feature & cross fade????

Is there something I need to do to make the keyboard typing "response" feature activate when I'm typing? I was under the impression that you're supposed to be able to feel something when you're typing. Also, is there something I need to do to make the shuffle feature work when I shake the touch? Nothing seems to happen when I shake it and I can't see what I need to adjust in the setting to make this work. Lastly, how can I set the cross fade feature this new model is supposed to have? Thanks guys!

Cross fade is not the same as gapless...there was always a feature in itunes where you could have the end of the song that was playing slowly decrease in volume and it would "blend" into the next upcoming song whose volume was slowly increasing. They would "fade" into each other. I loved that feature in iTunes, but it wasn't available on my Nano. Now I understand that this feature is available, but I find it hard to beleive they would put it into the Nano and not the touch.
Ah, I got your point! Well, this option is not available on the iPod Touch, nor I'm sure it's also available for the iPod Nano. Who told you that?

Ah, first I thought you were talking about having difficulties to something using the iPod's keyboard!
Now, I understand you're talking about the "Keyboard Clicks", which for at least on iPhone can be activated/de-activated. I don't have the iPod Touch anymore, but search on Settings for a Sound category!

Remote connection established - delayed ping responses - why??

When we have established a remote session with Cisco RAS it takes a long time - 30 secs to a minute - until we start to receive ping responses from a server on the network. Any ideas?

There is nothing wrong with the configuration because connection is established. With Ping command the normal response occurs in 1 to 10 seconds, depending on network traffic. But in you case it is taking more than 30m sec. this may occur due to big length cable use or traffic. To determine if ping is getting delay looked at the CPU.
