My mouse randomly moves and causes system to navigate to prior page

I am an animation and production student in college. I have to take tests on line. When in the modules my mouse will randomly move and navigate to the prior page which kicks me out of the site I was on. Unfortunately, when this happens I am not allowed back in the site to finish test. I have a MAC Pro desktop with Final Cut etc. Please help. Thanks

Which Mac Pro (number of processors or date or MacPro 3.1 designation or processor speed)?
How much RAM memory?
Which graphics card?
Which Mouse ? Wired? Wireless? Optical? mechanical?
What version Mac OS X?
Any custom Hardware?
Any external drives? which ones?

My two old white MacBooks run perfect with Snow leopard, but my 2011 17" i7 Macbook Pro is a dead slug with yosimite installed.
Tried the start with C held down, also with option held down. All it does is beeps at me three times, then again three times.....
I want to remove yosimite and install Snow leopard from dvd as yosimite runs worse than a Windows OS.
Can it be done, what do I need to do please?
Examples of faults, even with a 1tb solid state drive and 16 gig of ram, it is incredibly slow. Took four hours to install Logic 8 last night, I still have to reinstall logic 9 upgrade. On the White MacBooks I got both 8 and 9 installed in under an hour and a half all up.
Beeping on startup means failed RAM.
Slowness is usually caused by incompatible third-party system modifications.

How do I disable the reload on the back button of Firefox and have it display the cached/prior page version?

Every time I click the "back" button, Firefox reloads the previous page I was on. How do I disable the reload and have Firefox display the cached/prior page version? The whole point of going "back" is to see what we were just looking at.. I don't want a refreshed version of it. Any help would be greatly appreciated! I am running version 3.6.12.

No problem. It's not a request that's been seen much if at all to be honest. I rely on them myself.
You can always feel free to provide feedback to Apple though.

Mouse randomly moves around and clicks

Ok, so ive had this problem for a few months now and it has led me to the point where my mac was in storage and i havent touched it in a month or two. What happens is no matter what i am doing my mouse will move around the screen clicking randomly and basically doing whatever it wants. i have looked into the problem and other people have similiar issues but not the same. i can be across the room from my mac with the screen on, and the mouse will still move around and click and open countless folders even though no one at all is even near the computer. today when i took the mac out to see if there was a software update available (which there was) the mouse was not moving around or jumping at all througout the entire update. After the update it is now yet again jumpin around and clicking wherever it wants. Also its not just once in a while it is 24/7 it has made my mac unable to be used because you cant really control the mouse for more than a second at a time. my whole screen is now full of untitled folders.... any help would be appreciated...

Hi - I am having exactly the same problem. I am going to do what Barry said. Apple support says to do the following:
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.

X200s Wireless Randomly Turning off Causing System Freeze

Hi,
I've run into a problem recently with my 2009 x200s running Windows 7 Home edition.
Over the last day I noticed that after doing between 5-10 minutes of wireless web browsing, the system freezes. The exact moment this happens, I also notice that the wireless indicator just below the LCD goes from active to inactive. Further, while no amount of key-pressing does anything, including ctrl-alt-del, I can, amazingly, turn on/off the thinkpad lcd nightlight! The only way to recover from this is to press down on the power button for 5 seconds and reboot.
Then, 5-10 minutes later, the random freeze repeats. That is, with the wireless indicator light doing from green to dark.
By the third time this occured, I got a hint. I checked the event logs for anything unusual. Nothing.
I'm running a current version of Avast! antivirus and ran a Malwarebytes scan, again, nothing!
I'm at my wit's end. Any ideas from Lenovo gurus?
Help!
Best,
Dave

Ok, an update.
The freezing occurred while working in the library. That hadn't been a problem previously. So, why today?
I went home and tried it again. Everything seemed to work fine.
So, I guess my question now is this: Why would my x200s wireless connection stop working in a public access point causing a freeze in Win7 while working just fine at home??
Odd....

USB drive randomly disconnects (and causes deep traversal in Time Machine)

I have two external drives connected through a USB hub and they get sometimes randomly disconnected. Sometimes when I plug the drives in, only one appears on the desktop. Then I unplug them, plug them back in and just the other drive appears.
The other problem is that I back up one of the drives to the other using Time Machine and when the drive disappears by itself, Time Machine needs to perform deep traversal of the whole drive AND backs up the whole drive from scratch (see the console log below).
Any suggestions are appreciated!
Thanks,
Peter

The USB hub could have a problem (or not enough power); try connecting the drives directly to the Mac and see what happens. Is it a powered USB hub, and are the drives self-powered (i.e. each drive gets its own power from a wall socket/surge protector)?

Involuntary random mouse/cursor movement

Hi-my cursor seems to move when I am typing randomly, which means sometimes i can be typing away and suddenly i am typing in the middle of previous text. It also seems to randomly move and block text which means if I dont realise I end up deleting text.
Very annoying, any help much appreciated!
Thanks

Probably, without you being completely aware of it, you are lightly brushing against the PowerBook trackpad as you type. It can take some getting used to in order to keep your digits away from the trackpad as you type.
There is a setting to ignor the trackpad while typing. You get to that setting throught System Preferences.../Keyboard & Mouse/Trackpad. Click on the check box for "Ignore accidental trackpad input" and see if that helps.

Follow sprite when the mouse is down, but randomly move when mouse is up?

I have a sprite that has a Random Movement behavior.
While the mouse is down, I want it to stop this behavior and initialize a Follow Sprite behavior instead.
When the mouse is lifted, I want to stop the Follow Sprite behavior and reset/restart the Random Movement behavior.
Openspark helped me out with a different version of a very similar behavior a long while back, which worked. It switched between Random Movement and Draggable. I tried to edit the code so that it would apply to Follow Sprite instead of Draggable, but it isn't working the way I thought it would.
The order of behaviors on my sprite is as such:
followSprite (Follow Sprite)
moveToward (The behavior described above)
randomMove (Random Movement)
turnTowardsMouse (sprite faces mouse when it is clicked)
Face Destination (if not facing mouse, sprite faces toward the randomized endpoints generated by randomMove)
This is the moveToward behavior - the middleman that's supposed to be swapping between the two:
property pSprite
property pTouching
on beginSprite(me)
pSprite = sprite(me.spriteNum)
end beginSprite
on mouseDown(me)
-- Overrule the Random Movement and Rotation behavior until the mouse
-- is released. See the on prepareFrame() handler for the effect.
pTouching = TRUE
end mouseDown
on prepareFrame(me)
if pTouching then
    -- Block the event from reaching the Random Movement and Rotation
    -- behavior, so that only the Draggable behavior will work.
    if the mouseDown then
      stopEvent
    else
      -- The user has released the mouse.
      -- Start a new movement in the Random Movement and Rotation behavior.
      pSprite.pPath = VOID
      sendSprite(pSprite, #mNewPath)
      pSprite.pRotate = VOID
      sendSprite(pSprite, #mNewRotation)
      pTouching = 0
    end if
end if
end prepareFrame
Can anyone help me figure this out?
If you want to imagine a visual, it's essentially a touchscreen fish tank. Fish swim around randomly, but when someone is touching the screen, they approach the point of contact (which is defined by a tiny invisible sprite centered on the cursor).
Once again, thank you so much to anyone who can help me out. This is part of a capstone undergraduate art project I am doing - and I am far more experienced in making the visuals than I am in coding. I am having to mostly tackle Lingo on my own. Any coding help I've received will be recognized (with permission) on my artist website as well as a thesis paper I am writing that will be published in May.

As first steps at troubleshooting you could try an SMC reset and a PRAM reset:
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
Reset PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P and R.
You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
If that doesn't help, what OS are you running? Depending on the OS (Lion/Snow Leopard) will help determine the next step.

Safari causes system freeze during page load

Description:
I've been trying to figure this one out for a while now (about 2 weeks), without any luck. I've tried reading a couple of threads describing similar problems, but it looks like I've got something else going on here seeing as it affect the entire system. I appreciate any suggestion!
When a window in Safari is open and you're loading a page, it sometimes (almost always) causes a system freeze. Any action performed on any input device within OSX while a page is loading gets delayed by 5-20 seconds. Anything from right-clicking, to opening a new tab in Safari, to navigating to a new folder in Finder.... literally anything. The actual loading of the page is also affected by this. So when I click a link, the page becomes white and the system stalls. After X seconds, the system resumes and the page is displayed fully loaded. Once the page is loaded, everything is back to normal. I can just leave the Safari-window open without anything happening. It's just during the loading of a page.
Using the mouse to move and switch between open windows are the only actions I seem to be able to perform during the system freeze.
When it doesn't cause a system-wide freeze, it will still take forever for any page to load. Which isn't a problem in any other browser and I've never had any speed issues in general on any device.
What I know for sure is that I can solve the problem by closing all open Safari-tabs and windows or closing the app completely, and use Chrome instead. But I do like Safari, so I hope there's another way to fix this.
I should also note that I've made no changes to the system for many weeks now, other than installing whatever updates might have been available on the App Store.
What I've tried within Safari:
- program restart
- reset settings (every option checked)
- disable and remove extensions (only had one installed, LiveReload for Adobe Brackets)
- empty cache
- delete cookies
What I've tried within OSX:
- system restart
- complete OSX-recovery
- activity monitor (CPU, HDD and RAM always within normal values during all of this)
- checked HDD (successfull)
- checked internet-connection (got 50Mbit/s connection, no speed issues, checked on multiple devices)
- tried other browsers (Chrome (OSX) and IE (Win 7, Parallels) both run smoothly)
- turned off IPv6 in terminal (based on a suggestion here at the forums)
- disabled iCloud-sync
- disabled Dropbox
- probably a couple of other things i can't remember right now

So... I finally fixed it.
In addition to the things I mentioned I tried, I also checked if it could be malware-related. It wasnt. I then checked if it was just affecting my user-account or OSX globally. I created a new account and Safari ran perfectly. I therefore assumed it had to be something in my library-folder.
I deleted just about any mention of Safari in the Library-folder (the visible one) and just to be absolutely sure, I deleted the Contents-folder inside Safari.app in the Applications-folder. I then downloaded and installed Safari 7.0.3. Everything runs smooth now.

Random movement within an irregularly constrained sprite (EDITED)

(NEW EDIT AT BOTTOM)
So, basically, I'm making a little program that crudely simulates an ant colony. I have little tunnels the ant-sprites can travel down, as well as chambers, in an irregularly-shaped sprite.
I am not the most advanced at Director, but at least I've figured some things out. I found code on an open-source website (openspark, actually) that allows for an object to be dragged inside an irregular shape that has a matte ink.
It's all well and good that the ants can be dragged within this boundary, but is there any way to have them use a Random Movement and Rotation behavior that is confined by the same laws? Or is that impossible / extremely hard?
By the way, I already have a middleman behavior I use to toggle between dragging and random movement, so that does not factor into my question. I just need to know how to alter the Random Movement behavior so that it abides by the same constraint rules as my dragging behavior, if possible.
Here is the code I'm using for dragging. I made a couple edits from the original, but not much.
Don't worry about the canJumpGaps function of this code, as I am using a touch screen and it will never be used.
property spriteNum
property canJumpGaps
-- set to TRUE on mouseDown if the shiftDown
property pSprite
-- this draggable sprite
property pConstraintSprite
-- sprite to which this sprite is constrained
property pConstraintAlpha
-- alpha channel image of constraining member
property pOffset
-- offset between this sprite's loc and the mouse
property pCurrentLoc
-- last known position of this draggable sprite with respect to the constraining sprite
-- EVENT HANDLERS --
on beginSprite(me)
pSprite = sprite(spriteNum)
pConstraintSprite = sprite(1)
-- We'll use the value of the alpha channel to detect holes in the sprite
pConstraintAlpha = pConstraintSprite.member.image.extractAlpha()
end beginSprite
on mouseDown(me)
canJumpGaps = the shiftDown
if not pCurrentLoc then
    -- The user has not yet dragged the sprite anywhere. Find out its
    -- current position with respect to the constraint sprite.
pCurrentLoc = pConstraintSprite.mapStageToMember(pSprite.loc)
    if not pCurrentLoc then
      -- The mouse is not over an opaque part of the constraint
      -- sprite. It can't be dragged at all.
      exit
    end if
end if
-- Start dragging
pOffset = pSprite.loc - the mouseLoc
end mouseDown
on exitFrame(me)
if not pOffset then
    -- The user is not dragging the sprite
    exit
end if
if the mouseDown then
    me.mMoveSprite()
else
    -- The user just released the mouse
   pOffset = 0
end if
end exitFrame
-- PRIVATE METHOD --
on mMoveSprite(me) ---------------------------------------------------
-- SENT BY exitFrame()
-- ACTION: Calculates how near to the current mouseLoc the draggable
--         sprite can be dragged.
tMouseLoc = the mouseLoc + pOffset
-- Find where the mouse is with respect to the constraint member
tImageLoc = pConstraintSprite.mapStageToMember(tMouseLoc)
if voidP(tImageLoc) then
    -- The mouse is currently outside the constraint sprite. Use a
    -- slower but more powerful method of determining the relative
    -- position.
    tLeft = pConstraintSprite.left
    tTop = pConstraintSprite.top
    tImageLoc = tMouseLoc-point(tLeft, tTop)
else if canJumpGaps then
    -- Check if the mouse is over a non-white area of the constraint
    -- member
   tAlpha = pConstraintAlpha.getPixel(tImageLoc, #integer)
end if
if tAlpha then
    -- Let the mouse move to this spot
else -- Can't jump gaps or the mouse is over a gap
    -- Find how near the dragged sprite can get
    tDelta = pCurrentLoc - tImageLoc
    tDeltaH = tDelta.locH
    tDeltaV = tDelta.locV
    tSteps = max(abs(tDeltaH), abs(tDeltaV))
    if not tSteps then
      -- The mouse hasn't moved since the last exitFrame
      exit
    end if
    tSteps = integer(tSteps)
if float(tSteps) <> 0 then
tStep = tDelta / float(tSteps)
-- This makes sure I'm not dividing by zero.
else
tStep = 1
end if
repeat while tSteps
-- Move one pixel towards the mouse
tSteps = tSteps - 1
tLoc = tImageLoc + (tStep * tSteps)
-- Test that we are still on an opaque area
tAlpha = pConstraintAlpha.getPixel(tLoc, #integer)
if not tAlpha then
-- We've gone a step too far: move back to an opaque area
tSteps = tSteps + 1
exit repeat
end if
end repeat
end if
-- Update the absolute and relative positions of the draggable
-- sprite.
tAdjust     = tSteps * tStep
pCurrentLoc = tImageLoc + tAdjust -- relative to constrain sprite
tMouseLoc   = tMouseLoc + tAdjust -- relative to the stage
-- Move the sprite
pSprite.loc = tMouseLoc
end mMoveSprite
Thank you SO incredibly much to anyone who can help. This is for a senior project of mine in undergrad, and I really appreciate any help I can get. My resources on Director are limited, especially for odd issues like this.
EDIT:
So I found out that a way to do collision detection in Director is by using getPixel().
I found this protected dcr file that is a perfect example of the way in which I want my ant objects to interact with walls:
http://xfiles.funnygarbage.com/~colinholgate/dcr/irregular.dcr
I've been trying to build a getPixel() collision detection mechanism for hours but have been unsuccessful.
Basically, what I want the behavior to do is... get the pixel color of the tunnel sprite (sprite 2) at the center of the ant sprite. If the pixel color is white (the transparent background color surrounding the tunnel shape), I want to tell the Random Movement and Direction behavior this:
pSprite.pPath = VOID
sendSprite(pSprite, #mNewPath)
pSprite.pRotate = VOID
sendSprite(pSprite, #mNewRotation)
This tells the Random Movement behavior to stop moving and determine a new path. The behavior should probably also offset the center of the sprite by a couple pixels when this happens so it is no longer over an opaque area and the Random Movement behavior won't get stuck.
Will this work? If not, could anyone help me in building a collision detection behavior based on getPixel? This doesn't seem like it'd be all that difficult - at least in theory.

Hi Roberto,
I had an experience, which defies most common sense about data modeling. Moving from a cube to a ODS and then back on to a cube to introduce delta on a BPS delta application. It is a long sad disappointing store. But I had 24 keys (I know 16 is the max, I combined 6 keys into a single filed also had the same fileds in the data fileds, use these combination keys to deal with 16 key max limitation and adjusted during transformation.
It did work, but later gave up due to some other functional issues and we realized it is a bad experiement due to everyones data understanding.
I am saying is 16 key limitation is an issue, you can overcome with combining couple of fileds into a single filed in the start routine, map it and reuse it later.
Hope this gives you some ideas.
Goodluck,
Alex (Arthur Samson)

IPad mini randomly opens and closes apps, changes pages on book readers

My iPad mini has gone crazy, it randomly opens and closes apps, plays games itself, changes pages whilst reading a book, starts flashing. Tried everything, rebooted the device, updated it always with the latest software update and have reset the iPad as a new IPad with no success. The problem still occurs which is really enjoying. I checked on the Internet and I'm not the only one with an iPad mini with this problem. The iPad is older than one year, what are my chances of resolving this and how?

I have this problem with my PDFs too. I'm using a lot of PDFs from the German RPG "The Dark Eye" (Das schwarze Auge) from their the PDF shop "ulisses ebooks".
However, i recognized that I don't get this random black boxes after a restart of the iPad Air for a long time. But when it starts it's become very frequently.
To remove the black boxes for a single page i can close the book and reopen it or just mark text from the corrupted page. Zoom in removes the black boxes too, but if you zoom out there are visible again.
I also recognzied that this must be a problem if the iPads PDF engine and not from iBooks. I got the same random black boxes in a PDF which I viewd in Safari.
I think that changing the reader will only help if it has its own PDF Engine. Don't know if this possible in iOS.
Perhaps it's some kind of memory leak of the iOS PDF Engine, after this bug apperas only after some time of ussage.

Screen displays just a bit of "html", and none of the rest of the page

Every now and then, when I navigate from one page to another, all I see on-screen is the "greater than" sign and "html". If I press F5, the page displays properly.
What's going on, and how do I fix it?
Thanks,

The article also recommends the use of a third party utility, as Disk Utility is not able to repair this kind of directory error. You will need to have either Disk Warrior or Tech Tool Pro to have any chance of repairing the disk.
Your other option is to backup your HDD then completely reformat your drive (post back for step-by-step directions) then re-install the OS and recover your data from the backup.
Please do post back with further questions or comments.
Good luck.
