HT1338 My mouse cursor dissappears for up to 20 seconds quite often. What's up?

My mouse cursor keeps dissapearing erratically for 10 to 15 seconds at a time. Typing also seizes, then catches up. Running Mackeeper daily and cleared my disk utility permissions to no avail.... Help!

I've red through the P67 errata about USB and all of them have the status "No Plan to Fix". As being quite familiar with the USB 2.0 specification (I've once written an USB driver for an embedded system myself) I do not see any issues mentioned that could be related to enumeration problems during cold boot or resume. This seriously doubts me that the B3 release will fix my issue.
I will also put this problem in MSI support, but knowing how they did reply in my other issue report about the mouse not working in my BIOS I'm not so sure if they will take it seriously....

How to control the movement of mouse cursor?

Hi,
I would like to ask
how to write a java program to control the movement of mouse cursor?
For example, when I press the "��" key on the keyboard, then the mouse cursor move upward.
Thanks you very much

I keep loosing my mouse cursor !!!

Hi,
annoying problem developing. I have two 17" monitors - ie 34" of desktop space. Both monitors are running at quite high resolution. Which is a problem as everytime you start typing, Tiger makes the mouse cursor disappear and consequently i end up loosing track of where my cursor is on the screens. So I was wondering if people knew of a sane solution to locating my cursor quickly, apart from having to park it in one location everytime.
help greatly appreciated

Hi,
I had that problem too.
I resorted to Universal Access preferences-Mouse-Cursor size for a jumbo size cursor.
And also run the Dock at left side of screen with magnification on, then as a last resort I can move the mouse hard left + up/down to provoke the Dock.
I think somewhere there was a key combination to flash the cursor, but I can't find it (maybe some other OS or a Dashboard widgit).

Please help: Mouse cursor on MBP repeatedly freezing for a few seconds

Hi all
I bought a MBP last week, and today I started experiencing problems with the mouse cursor. No matter whether I'm using the trackpad or an external mouse (I've tried using both a wired Mighty Mouse and a wireless Logitech), when I'm moving the cursor it keeps freezing for a few seconds (perhaps less than a second), and then I "regain" control of it, only for it to freeze again after a short while.
The only thing that I can think of that might have something to do with this is that I replaced the 2GB of Apple RAM with 4GB of OWC RAM a couple of days ago. Can this be the reason?
Please help me, as this problem renders the computer impossible to use:(
Thanks in advance
Daniel
PS: I'm running Mac OS 10.5.1 and I've got the Keyboard Freeze Update Installed.

Hi.
I have a similar problem, however I realized it is somehow related to weather the airport is on. If I turn it off, there are no freezes. It is weird, and I'm going to go with it to Apple.

Hide the mouse cursor for whole application

I can hide a mouse cursor for my frame with following code:
int[] pixels = new int[16 * 16];
Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16));
Cursor transparentCursor =Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0), "invisibleCursor");
myFrame.setCursor(transparentCursor);What is the simple way to set the cursor invisible for all current and future childs of my frame?

hi,
write a new class for this: class CursorHandler
private static Vector frames = new Vector ();
public static void addFrame (JFrame f)
    frames.add (f);
public static void setCursor (Cursor s)
    for (int i = 0; i < frames.size (); i++)
      JFrame f = (JFrame) frames.get (i);
      f.SetCursor (s);
}then just do:CursorHandler.addFrame (this); //for all frames
CursorHandler.setCursor (new Cursor (Cursor.WAIT_CURSOR)); //in any framegreetings,

X300: TrackPad will not move mouse cursor for several seconds after clicking any TrackPoint button

I have a new X300 with a clean install of Windows XP (SP3) and all of the latest drivers from the Lenovo website. Whenever I click any of the three TrackPoint buttons, the TrackPad is not able move the mouse cursor for about 2 seconds. During this time, I can still move the cursor with the TrackPoint. I did not experience this behavior with my previous laptop, which was a ThinkPad T42 running Windows XP (SP2).
Thanks for any suggestions!

I once installed XP using my great Unattended-selfmade-fullypatched-etc-DVDs (I call it Windows XP Ready to Go Edition) on my X300 and had zero problems. This is also based on SP3.
Perhaps the order of installing servicepack and several drivers is important.
I start off with an SP3-integrated installationof Windows XP, patch it fully first and then go on with driver updates (Chipset first, then ACPI, LAN, WLAN, Sound, Graphics, Input devices.
At least its possible to get it working flawlessly, my Installation proved that.
I WOULD NEVER RECOMMEND INSTALLING SP3 AS AN UPDATE, ONLY START FROM SCRATCH USING AN SP3-INTEGRATED SETUP.

"Drag" and "Drag lock" indicator for the trackpad (mouse) cursor

Anyone know how to get a "Drag" and "Drag lock" indicator for the trackpad (mouse) cursor. When using the track pad, I'm often finding that my final click does not release the item I was dragging and then I inadvertently drag it across my screen, as I go to my next function. Would be nice if there was some type of indicator that would pop up on the cursor so you knew when drag lock is active.
Thanks!

Idiot question - How do I re-install Leopard? No matter what I do, it kicks the disk out on restart. I have tried using the 'install' command on the disk, nothing. It kicks the disk out and boots from the hard drive. I have tried rebooting holding down the 'c' key to force it to read from the drive, it still kicks the disk out and boots from the hard drive. What else should I do?
I researched back further and found another thread where people were complaining of the same drag and drop issue: http://discussions.apple.com/thread.jspa?messageID=6446208
Someone suggested a solution involving permissions. I fixed my permissions. Drag and drop is still not working.
There was also a set of commands to type into terminal that would supposedly fix the issue, or perhaps it was a Spotlight issue that the thread had morphed into. I did that. Drag and drop is still not working.
Am I just totally hosed? Help!

[SOLVED] Putting mouse cursor on system tray = freeze for 1~3 sec

Hello guys, I got 2 problems with setting up my graphical package or something.
1. I've installed "Arch 64bit + Openbox Stand alone + Catalyst" on my desktop.
When I put my mouse cursor on the system tray, whole system freezes for 1~3 seconds.
2. When I open "Thunar", randomly icons and fonts are blurry. Sometimes it opens clearly but sometimes not.
There is no problem at all when I install "ArchBang 64-bit". This seems to be that I missed to install some specific package.
Any idea?

This is a strange problem, and probably something stupid I've done. If I move my mouse to the lower right hand side of the desktop
(bottom panel or system tray it freezes for a second or so).
This problem is repeatable on Xfce4.8 and also E17 desktop.
I have a microsoft optical mouse, so its not (mechanical mouse ball). More specifically I'm running at 1280x1024 res and the area
where the mouse pointer sticks is about 4cm from the right hand screen edge and 1cm down.
I am using an Ati Radeon HD4770 card with the proprietry fglrx driver Catalyst 11.5 and graphics acceleration is fine.
My /etc/X11/xorg.conf below:
Section "ServerLayout"
Identifier "aticonfig Layout"

EndSection
Section "Module"
EndSection

Option    "ModelName" "Generic Autodetecting Monitor"
Option    "DPMS" "true"

EndSection
Being lazy I actually used this xorg.conf from PCLinux but I dont have the same mouse probelem on E17 or Xfce in PClinux.
When the freeze occurs I cannot use keyboard, then about a second later, I have control again. The system works normally and no
errors are wrote to /var/log/messages.
Only thing I can find in /var/log/Xorg.0.log is a warning:
[ 3651.919] Warning: LookupWindow()/SecurityLookupWindow() are deprecated. Please convert your driver/module to use dixLookupWindow().
Before using fglrx I was using the radeon driver. This is probably something stupid on my part, I am installing a new hard drive shortly so will
be re-installing.
The problem is as if some application is stealing the mouse focus, but I cannot understand why it is happening to that specific area on the screen.
Thanks in advance for any insight.
Some hardware:
Intel i5 750
Gigabyte GA-P55A-UD3 (Intel P55A chipset)

HT1338 My MacBook Air is very slow. Every time I click the mouse, the spinning wheel appears and remains for up to 30 seconds. Can you help me?

My MacBook Air is very slow. Every time I click the mouse, the spinning wheel appears and remains for up to 30 seconds before the screen changes. This has been happening the past 24 hours. Any ideas?

First, back up all data immediately, as your boot drive may be failing.
If you have more than ten or so files or folders on your Desktop, move them, temporarily at least, somewhere else in your home folder.
If iCloud is enabled, disable it.
Disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable. Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

Mouse cursor disappears sometimes on Firefox for Mac

Sometimes, only when Firefox is open, the mouse cursor disappears. I can still click, but the cursor is invisible.

Does the mouse pointer only disappear when the pointer is in a Firefox window (user interface or browser part or both) or is it gone outside Firefox as well?

Mouse cursor keeps disappearing under 10.7

Ever since I've installed 10.7 I notice that the mouse cursor has a tendency to keep dissappearing in most apps, particularly Safari. For example, like when I click a text box to type an email in Hotmail. The cursor dissappears and only re-appears when I move the mouse to get the cursor out of the program app. But after it reappears, I got back to Safari it gets hidden again. This is very frustrating indeed as I have no idea where the mouse is on the page.
As a matter of fact, as I enter this question in the text box, the cursor has completely dissappeared and only reappears (but then quickly hides again) when I go inside and outside of the text block. I know normally the cursor would dissappear when I started typing, but this happens even when I'm not and I'm shaking the mouse to try to unhide it
However it seems to happen in other apps as well, but is most frequently happening in Safari probably mostly since that is my most common app.

The cursor dissappears whenever you type on the keyboard. It just always happens globally.

HT1338 My mouse cursor dissappears for up to 20 seconds quite often. What's up?
