Keyboard input lost on desktop actions

If I change the name of a file on the desktop, I find that often this can result in complete loss of keyboard input as far as file names are concerned – i.e., it becomes impossible to change file names, name new files or make any keyboard input whatsoever. This can happen almost at once, or after an indeterminate number of file names have been changed; there seems to be no pattern or logic to the phenomenon. Suggestions?

I am having a hard time finding any common thread to this event. The last time it occurred, last night, I was running the following applications:
Firefox v 2.0.0.1
Entourage v 11
Word 2004 v 11
Photoshop CS v 8
Preview v 3.0.7
QuickTime v 7.1.3
Silverfast launcher v 2.1.2
Microtek Scanner Finder v 3.24
Otherwise:
Startup item: Microtek Scanner Finder v 3.24
APE extensions: Don't think any; I don't recognise the term.
Attachments: Printer (Epson Pro 3800), Scanner (Microtek i800), external hard drive, USB modem. However, I had these attachments even before the problem cropped up.
Finally, I have also run repairs and permissions corrections from Disk Utility without discovering any problems.
Many thanks for your help!

Keyboard input delayed in Siebel application // letters lost while typing

Hi all,
We have a strange problem on a client computer. While working with Siebel, keyboard input is extremely delayed. When typing a word or a phrase, it takes some seconds to appear in the corresponding field, and also some chars are just lost if one is typing too fast. This does only happen in Siebel - all other applications are OK.
I have seen this already some months ago, but don't remember the cause.
Web Client 7.8.2.14 QF0E76
Win XP SP3 IE8
Did anyone ever experience this? Might be some specific driver issue or IE security update or whatever?
Thanks

Thanks Wilson for your input, unfortunately resetting browser settings and stuff like this does not help.
In the meantime I have done more research on this and found something interesting. The dropped characters / missing keystrokes do only appear when typing in Siebel popup applets. We do NEVER lose any keystroke when typing in a normal form or list applet. I have run a little test with a vanilla SRF file and a VBS Script.
I placed a VBS file on my desktop which will use SendKeys to simulate typing the word "Siebel" several times.
The source code of the VBS file is:
>
Option Explicit
Dim WshShell, c
Set WshShell = CreateObject("WScript.Shell")
c=0
WScript.Sleep 5000
Do While c < 5
WshShell.SendKeys "S"
WScript.Sleep 70
WshShell.SendKeys "i"
WScript.Sleep 40
WshShell.SendKeys "e"
WScript.Sleep 30
WshShell.SendKeys "b"
WScript.Sleep 90
WshShell.SendKeys "e"
WScript.Sleep 120
WshShell.SendKeys "l"
WScript.Sleep 70
WshShell.SendKeys " "
WScript.Sleep 90
c = c + 1
Loop
WScript.Quitwhen I click this script I have 5 seconds to switch to Siebel and point the cursor into a text field.
-> When this text field is on a form applet, it correctly writes "Siebel Siebel Siebel Siebel Siebel"
-> When this field is on a MVG applet, it sometimes drops keystrokes like "Siebel Siel iebel Siebel Sibel"
what the hell could be the problem ??????
Could someone try this in another environment??
We are on 7.8.2.14 QF0E76 ...

How to have same keyboards input source in Mac and Windows???

Can anybody help?
Thank you

Can I use an AirPort Extreme Base Station "n"
Yes.
and if so, will my MacBook work with this at maximum download / upload speed (i.e. equivalent to the cable)
The speed of your internal network generally is much much faster than the speed of your internet connection. Unless he has an internet connection faster than approx 6Mbps then even dropping down to the old 802.11b Airport would not seen any decrease in speed of downloads etc...
and will my brother's PC's also be able to connect?
If his PC is 802.11b/g-compliant, it shouldn't have any problems connecting to the AirPort base station.
Or is there another Airport base station?
The other AirPorts would work, but the AirPort Express & older 802.11g AirPort Extreme base stations have a max. range of 150 feet.
OR-- should I head down to "Generic Computer Store" and just by a wireless router (WiFi)(think that's what they call them) and connect this to his cable modem? IF SO WILL THAT WORK FOR MY MAC?
That is always an option as well, especially since he will be the primary user throughout the year. I'd suggest going with a brand name, like Belkin, D-Link, or Linksys for the wireless router choice.

Installed rdesktop - but keyboard input still goes to Mac Terminal??

My work PC has been "upgraded" to Windows 7 which made the Microsoft Remote Desktop Connection v2.0.1 stop working (it connects OK, I can login and see my work PC screen, but as soon as I try to do something I am "disconnected" from the PC). I can't install RDC 2.1 because I have a PPC G5.
So I searched for alternative remote desktop apps. Cord 0.5.0 crashes on my machine and 0.5.5 won't even start up.
I ended up installing rdesktop (www.rdesktop.org)
It looks promising - very fast, and gets me to my PC login screen. My mouse pointer can click on the screen buttons, but any keyboard input appears in my G5 Terminal window and is not sent to the Windows 7 PC. This makes it impossible to enter my Windows 7 password to login!
I'm sure this is a simple problem to solve but I have no idea on how to solve it.
Any clues appreciated. Thanks.

Try:
rdesktop -x m -r clipboard:"CLIPBOARD" -g 1280x1024 -u<username> <hostip>
I do recommend using ssh tunnel for RDP over internet. Is more secure and limits open ports to only ssh port in firewall.
There are instructions about on how to use cygwin with RSA key login, turn off ssh password login when working properly.

Subtle Window Manager Blocks All keyboard Input?

So I'm trying to use subtle on a headless server box of mine over a tightvnc server. Yet for some reason all keyboard input is blocked. If I'm using twm instead, everything works fine.
~/.vnc/xstartup
#!/bin/sh
export XKL_XMODMAP_DISABLE=1
xrdb $HOME/.Xresources
xsetroot -solid grey
#exec ck-launch-session subtle &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
subtle &
Again, I can type into xterm when I'm using twm, but not when I'm using subtle. Anyone else know of some sort of work-around that they've used with the same or possibly another WM?
Thanks!

Via xinit? That worked, but I don't really want to use the root display for it, just in case I need to do some maintenance on it at the machine . (I do blind command manual maintenance sometimes just because it's easier.
Is there possibly another way other than using xinit and x11vnc or that does what I want it too?

Reader Closes on any Keyboard input

Has anyone had this problem?
Reader closes on any keyboard input.
Mouse works fine. And I mean any keyboard action at anytime.
I have tried uninstalling all adobe reader apps/plugins and reinstalling the latest available version but still Reader closes with any keyboard input. Make opening password protected PDF's impossible. The "find" function unusable.
Any Ideas?

Are you trying to run your application through TextPad, or some IDE? The System.in is best for command prompt input. Trying running your program through the command prompt, and it should work fine.
I replicated your error, running your application through TextPad.

Firefox not responding to keyboard input

I'm having issues with Firefox temporarily no longer responding to keyboard input.
I have two machines, both running Windows 7. On my laptop, I never have any issues but on my desktop, I find that Firefox sometimes blocks keyboard input. It will allow me to enter one character in any text field, and no more. Any further input is ignored. This applies to the address bar, the search box and any text fields in the displayed web page, in any tab. All keyboard navigation seems to also be ignored.
I've tried Reset Firefox and Safe Mode, they don't appear to change anything. I've also tried uninstalling Synergy and changing from my regular English-International keyboard layout to US English, but this still seems to occur. I am also running Workrave which can interrupt keyboard input, but since I can add 1 character, I suspect that Workrave is not the problem.
Sometimes it can seemingly be unblocked by pressing Start+F9, CTRL+SHIFT+ESC, restarting firefox or opening a new tab, but this seems to only be a temporary solution, the problem soon reoccurs. This bug has been present for some time, I first noticed it in v28 (although it may be even older), I am currently using v31.
One thing I've noticed is that it never occurs until after my screen has been locked at least once.
The trouble-shooting information attached will not be entirely accurate because I'm using my laptop to type this - Firefox is not accepting keyboard input right now on my desktop! However, the two environments are similar.
Thanks, Tadhg

Some have reported that pressing F9 and the Windows key simultaneously one or more times has worked to fix issues with the keyboard not working.

Keyboard input delay Flex/AIR

I've build an AIR desktop app that uses an USB barcode scanner. To capture the token provided by the barcode scanner an input field is used.
When testing the barcode input was only partially captured by the scanner. This was caused by the barcode scanner's input coming in the fast. Increasing the key stroke delay of the barcode scanner (config tool from motorola) solved the problem however this is not ideal.
Does anyone has experience with this type of problems? What is an approach to solve this? Maybe by writing an Java compagnion app that captures the keyboard input?

I just ran into this same problem. Our users are scanning barcodes from various labels using various types of scanners (changing the delay using scanner software wasn't an option). We also have to allow them to scan to a TextInput within a DataGrid, which created even more problems. There were 2 very interesting things I learned in coming up with a solution for this one:
1. As mentioned previously, the scanner inputs the data so quickly that the enter key event is often processed before the change event for the text. I tried several solutions (like trying to force the change event before the enter key is processed), but learned that the best solution was just to add the delay as mentioned in previous posts.
2. When adding to a DataGrid control, I learned that both the DataGrid's & the TextInput's key down events are fired by the same SystemManager event. Though you can override the TextInput's keyDownHandler, you can't override the DataGrid's because it's a private method. So, even though my delay was being processed in the TextInput, the DataGrid was forcing control away from it and moving to the next item in the grid. To get around this one, I had to stop propagation of the event from the TextInput, then re-start the DataGrid's event once the delay was complete. I also had to process a focus-out event to get it to move to the next item in the DataGrid.
Here's the code I used inside a custom TextInput control to handle processing both stand-alone and inside a DataGrid:
override protected function keyDownHandler(event:KeyboardEvent):void
      // If the enter key was pressed, then we need to add a delay.
      // Barcode scanners quite often process the enter key before the TextInput
      // control has time to finish processing all the text. (e.g., Instead of
      // getting 12345 as a text entry, you could get 123 or 1234.)
      if (event.charCode == Keyboard.ENTER)
           // If this is the first time we've processed the enter key, we need to
           // add the delay.
           if (_keyboardEvent == null)
           _keyboardEvent = new KeyboardEvent(event.type, event.bubbles,
           event.cancelable, event.charCode, event.keyCode, event.keyLocation,
           event.ctrlKey, event.altKey, event.shiftKey);
           event.stopImmediatePropagation();
           barcodeTimer(_keyboardEvent);
                      return;
           // If the enter key is pressed while we are still in the delay, ignore
           // it.
           else if (_keyboardEvent != null && _keyboardEvent != event)
                     return;
           // If the delay is complete, then we need to restart events related to
           // the enter key so the control is handled properly.
           else
                super.keyDownHandler(event);
                // If the TextInput is inside a DataGrid, then we need to dispatch the
                // DataGrid's key down event. We also need to make sure the proper
                // focus change happens (since this was stopped in the original event
                // propagation).
                if (parent != null && parent.parent != null &&
           parent.parent is mx.controls.DataGrid)
           parent.parent.dispatchEvent(event);
           dispatchEvent(new FocusEvent(FocusEvent.KEY_FOCUS_CHANGE, true,
                          false, null, event.shiftKey, Keyboard.TAB));
        _keyboardEvent = null;
                return;
      super.keyDownHandler(event);
* This is a copy of the keyboard event to be processed once the barcode
* delay is complete.
private var _keyboardEvent:KeyboardEvent = null;
* This method launches a timer of sufficient length to allow barcode
* scanner text to be processed before it re-launches the keyboard event.
* @param event This is the key-down event to be restarted once the timer is
* complete.
private function barcodeTimer(event:KeyboardEvent):void
      var t:Timer = new Timer(30, 1); // 30 ms
   t.addEventListener(TimerEvent.TIMER,
           function():void
           keyDownHandler(event);
   t.start();

Keyboard Shortcuts? Show Desktop?

Is there a possible keyboard shortcut to "show desktop"? I can't seem to find one on the macbook...

you can program 'hot corners' on assign a particular key to do that. here are the steps for each
Hot Corners: You can go into one corner of the screen and the computer will perform the assigned action. 1. go into System Prefs 2. Click 'Exposé and Spaces' 3. Click the scroll menu of the corner you want to activate and scroll down to 'Desktop' 4. Go all the way into that particular corner and the desktop should appear. Go back into the corner to show all your windows again.
Assigning a Key: 1. On the same pane as Hot Corners, click the scroll menu next to "Show Desktop" and click the key you want to assign to show the desktop when pressed. Make sure that this key has no other function, such as volume or brightness.
I know that's a lot of info, but it's worth writing it

Keyboard Input, Contextual Menus Slow to Respond After Restart

Immediately after a restart I must log out and back in one or two times in order for keyboard input (mostly command-tab) and contextual menus to work as expected, i.e. instantaneously. As it stands, a 2-3 second delay occurs between an action and a result.
Why does logging out and back in alleviate this problem?
Thanks.

Hi,
your success gives me great pleasure, congratulation for your second "first steps"!And by the way: much of that I know now it's due to the ideas, questions and help from the people here in the forum.
Because of your enthusiasm for DW, which I share, you would accept my new suggestion. Take a look hereby:
Maybe you can make that gap a litttle bit smaller between the menu and the submenu by changing your css, anyhow.
As for the </ br>: You are absolutely right! In design mode you could use "shift enter".

P.S.
Kindergarten! not kindergarden! I am very pleased to see that.

Keyboard input changed to wrong language

I'm using a dual g5 desktop running tiger 10.4.4. This morning all keyboard input is in the wrong language. It's greek or one of the symbol fonts. According to the setings in the international panel everything should be set to US English, roman script. I know that CMD+space used to toggle between input choices but that now brings up Spotlight. Is another key combination that toggles the languages? Other settings to check? It's interesting that the input menu tab of the international pane still says use CMD+space to toggle inputs, but that no longer works.
Help? thanks

According to the setings in the international panel
everything should be set to US English, roman
script.
The setting that matters is system preferences/international/input menu (not languages). Also make sure you have the box checked for "show input menu in finder," so you can see what keyboard layout is active in the "flag" menu at the top right of the Finder.

Keyboard input errors

I have lost all reliable keyboard input to my G4 powerbook running on OSX 10.4. I have been able to run Tech Tool, Disk Repair and Repair Permissions. I don't have another users account and without the necessary input, I cannot sign-in as another user.
In all areas where text can be typed in, Text Edit, Apple Works, Authentication etc., if I get anything it is not close to the keystroke.
I show over 37gb available on a 80gb hard drive.

Hi, Melvin. If your keyboard is typing a lot of numerals instead of letters, press the Num Lock key (F6) to turn off Num Lock.
If that's not the problem, connect a USB keyboard to the Powerbook and see whether it misbehaves in the same way. If it does, there's a software glitch behind the problem. To confirm that, boot to a CD or DVD. If the problem disappears, software on your hard drive is definitely at fault. In that case, while booted to the CD, run the Repair Disk and Repair Permissions functions of Disk Utility to square things away on the internal HD. Failing that, an Archive and Install of OS X should put things right.
If a USB keyboard behaves properly when connected, your built-in keyboard or its connection to the main logic board has gone bad. To determine which it is, release the keyboard, flip it over onto your Tibook's wrist rests, and gently disconnect its ribbon cable from the logic board, then reconnect it. Put the keyboard back and test again. If the problem persists, replace the keyboard.

Keyboard input change after Mavericks update.

I am currently using a MacBook 13 inch unibody and since the update to Mavericks my keyboard has changed. I use a Japanese keyboard and have now lost the abilty to enter the at mark @ (that was copied and pasted). A lot of the other keys have moved. I have checked the keyboard input sources and there is only 1 listed for Japanese (kotoeri) which used to work before.
Any suggestions would be much appreciated.

Apple seems to have gone back to the old system where Kotoeri uses the last-active keyboard layout. Try switching to US in the "flag" menu before switching to Kotoeri and see if that works.

TS3280 How can i enable both paired bluetooth and ios keyboard input at the same time?

How can i enable both paired bluetooth and ios keyboard input at the same time?
This is needed for the app im working on. Need some user input via keypad as well as scanner input via a paired bluetooth scanner.

You probably should not be using a keyboard bluetooth profile for a scanner, I am not a developer for apple so do not know the location for you to find out the correct profile you should be using for an input device that is not a keyboard. Sorry,
I am sure if you navigate the apple developer site you will probaly finmd what you're looking for.
