Secondary monitor taskbar disabled

Since August Patch Tuesday [2014], at least I think after these patches, something annoying happens with secondary monitors taskbar, it simply disables. Right click and select properties, then just ok it (without any changes) enables it again.
It seems to happen after a rdp connection to it.
As mentioned, not serious, but a bit annoying.
Workaround ? Settings ? Microsoft: Change ?

Yes, enabled (option checked), settings exactly as T.Kujala's screendump.
PC model (1) = Fujitsu <something>
PC model (2) = Home brew from different parts, ASUS MB, Intel i5 something etc. etc.
I think model is not relevant, the problem exists both at my work and at my home office, running totally different PC models, different windows domains, different graphic card types, different screen types, different most other except Microsoft account, operating
system and windows updates.
Based on the fact that the "problem" shows up on 2 totally different machines (and only after this August Tuesday patches and the non-serious nature of the problem, I am not willing to put a lot of work into this.
If Microsoft asks me to generate some kind of logs, reports etc. to be able to find the cause of the problem, no problem as long as it does not introduce lots of work or risks to my installations.

I have just upgraded. AND now I can't view video fullscreen on my secondary monitor?!! Why!

I have a dual monitor set-up, with sharing. I am on a Mac OS X Version 10.7.5
I am viewing my Firefox window on my secondary monitor. (NOT Primary) When I click any video to full-screen it loads the full-screen on my primary monitor. When I click the window to full-screen (on my secondary monitor) it fills the primary monitor.
Before I upgraded, this morning, I could click the full-screen button and my video would appear on the secondary monitor. (The same monitor.) Before this morning, I could re-size the browser window to full-size and view it in my secondary monitor. (The same monitor!)
So, explain to me, why the change? Why is it when I click on a video to enter full-screen, or want to re-size a window to full-screen on my secondary monitor, it views on my primary monitor. Does this make any sense?
Why? Why would somebody want to browse on one monitor, want to watch something fullscreen, click a button and then watch it on another monitor? I just don't get it. Or why would someone be browsing in a window on one monitor, click full-screen, and want to browse in the same window on another monitor?
I am sitting here facing my secondary monitor (which I use as my art-board) and my primary monitor sits to my left. I mainly work from my secondary monitor, so when I am drawing, painting and designing my cursor doesn't 'run into' my dock features, calendar, ext. When browsing in Firefox my window is where it should be, in-front of me. So why would I want to watch a video or browse the web on my left? Why? Why would any developer or designer do this! Especially considering the second, non viewing screen is black! Which means my secondary monitor (in-front of me) is black.
When I click, view full-screen, whether video or resizing windows, whether it is my primary or secondary monitor, don't you think the screen should appear full-screen in the monitor I am using?! Right?! I mean somehow you calculated a way for Firefox to recognize which monitor to reopen in. So what's up? I didn't have this problem last week? So tell me . . . why can't I open a video in full-screen on my secondary monitor like I have been doing for years? Why am I even having to write a complaint about something I used to be able to do. AND NOW I CAN'T.
I just checked Safari. Wow. Look at that! When I want to view a video in full-screen in the appropriate monitor I can! Wow! I can actually click on my secondary monitor and it's recognizes I want to watch the video on the same monitor.
I used to be able to do this in Firefox. I guess it is time to give up on Firefox. And choose a company who understands user-perspective. Or at-least understands what an upgrade is.

All my Adobe Reader (PDF) files are opening only in the secondary monitor by default, as I am workin

I am using Adobe 8 Professional and working on Windows XP. I have been facing an issue lately with opening files in a dual-monitor environment. All my Adobe Reader (PDF) files are opening only in the secondary monitor by default. There are times when I work only in one monitor and when I open a PDF file and want to have a look at it, I have to connect another monitor to view that file, since this file is open in the secondary monitor. It is very disappointing with such instances happening with Adobe (a leading organization). Can you please help so that the Adobe Reader files open in the primary monitor by default?

Firefox 10: Bookmarks menu flickers and is unusable on secondary monitor

Playback sluggish on secondary monitor

Now here's an interesting conundrum: Why is video playback choppy on my secondary monitor? I don't see this problem with other playback applications, including Quicktime Player--even when playing the same file!
This wasn't the case with iTunes 6. Video playback seemed much more responsive in general under v6, in fact.
This isn't a dealbreaker, of course, but I often like to watch a podcast on my secondary monitor while surfing or answering e-mail on my primary.
(And yes, I realize that 64-bit Windows is still technically unsupported.)

Bizarre... Must be some ATI driver incompatibility.

Java swing popupmenu / context menu does not appear in secondary monitor

Main screen left
second screen right
swing portal application is visible on two screens.
If you open a context menu (right mouse) on the right screen, the context menu open on the left (Main) screen instead of the right.

Thank you very much for the replying.
The below are my use cases :
1. JDK 7 used.
2. OS - Ubuntu/windows XP/2008
3. Tested with extending more than 1 monitors, i.e. Laptop / primary monitors are attached with other secondary monitors attached and then running swing portal        application.
4. This happens when you use "Extended Desktop" with two screens.
    Main screen left
    Second screen right

Maximizing videos in secondary monitor makes cursor disappear in main Max OSX

What the label on the can says. I have a dual monitor setup on my Mac, and when I maximize the video in my secondary monitor I can't see my cursor in the main monitor. If I click into the maximized video the cursor reappears, but once I move the cursor back into the main monitor I lose sight of the cursor again. This is very annoying, as I often watch videos in my secondary monitor and need to continue working in the main monitor.

Secondary monitor on 20"iMac, How to set portrait orientation when running

How do you set the display rotation in Windows XP?
I have a secondary monitor (wall-mounted at 90 degrees to normal) that OS X handles just fine (the display preference window provides a rotate function). However, when running Windows XP, the secondary monitor is still available, but I can not find a setting that will rotate the display. I downloaded the Apple Boot Camp ATI driver from AMD's site and the driver version went from 8.39 to 8.43. Still no visible way to rotate the secondary display. I then upgraded Boot Camp to 2.1 after which the ATI driver version went to 8.45. Still no rotate functionality.
I have tried using the ALT-OPTION-ARROW key with no success (recommended on some obscure Windows XP forum). I also downloaded the Apple Boot Camp Crystal Control Center from the AMD site, but it would not execute after installation (this upon yet another obscure recommendation).
I also have Windows XP on my MacBook. It uses an NVIDIA driver and it will allow display rotation.
Any help or advice is appreciated.

Updating my original post:
I have resolved the issue. The ATI Catalyst Control Center app (I meant Catalyst, not Crystal in my original post) needs Microsoft's .NET Framework 2.0, which was not included in my original Windows XP installation.
After downloading and installing the .NET Framework 2.0 package and reinstalling the Catalyst Control Center app, I am now able to rotate the secondary monitor display to the portrait orientation.
I use the secondary monitor primarily viewing on-line documentation while working with an application on the primary screen. The portrait orientation provides a much better environment for reading documentation as I can view 2+ pages at the same time.

Lenovo 3000 and a secondary monitor

I have a Lenovo 3000 V100 Laptop. I want to use a secondary monitor/display. I see the display on both the primary and secondary monitors until windows finishes booting and then the secondary monitor goes blank. I try FN F7 to no avail. I am using windows XP. I assume this is a setup problem.
Please advise.
David

Not having your exact model, try this.
Go to your desktop display.
Position your pointer over part of the display without any icons, open windows, or tasks.
Right click.
A menu should appear, click on "Properties" or "Graphics Properties" whichever is on the menu. This should open another menu, one tab on which can be selected to allow you to display the same thing on the internal and an external monitor. The graphics adapter software on my Lenovo displays its menu this way. I'm not sure if going through the Control Panel selection will get you to the same point.

Is it possible to force a fixed Application to open in a Secondary Monitor?

This is my first time actively using a forum, so forgive me if I'm unclear with my question or if I'm unaware of forum common sense or etiquette.
I've been running a Multi-Monitor system for awhile now at my office. I ran into a few problems when I first set it up, but was able to resolve many issues with many work-arounds. In truth, this is one of the same major problems I was having before.
As it says in my details, I have an iMac with a Wacom Cintiq 21UX via Mini DisplayPort to DVI, and an Apple Cinema Display via Arkview USB Display Adapter. I do a lot of graphical work amongst my many tasks, so the Cintiq is typically my main input device. I have it set in a Portrait position, which I prefer greatly over Landscape.
My problem is that to use many of the graphical applications, Adobe anything, I have to set it as the main monitor. Since Apple doesn't use application containers, at least, not in a way that allows you to drag the main toolbar. This solution, of course, I learned after a lot of struggle. It works and I'm fine with it now, but I've recently been called upon to use Final Cut and Motion for some projects and this problem has again reared its head, but in a different way.
I've programs set up all over my three screens; sized and set to where I like them and are most efficient, and across multiple Spaces. To properly run Final Cut, a resolution of 1280x800 is strongly recommended. Since I'm running Portrait, mine is set to 1200x1600. I didn't think much of Final Cut's initial warning at the time, since any windows caught outside the screen I was certain I could rescue with a trusty Applescript, written to collect all windows to the main screen. Which I discovered was a problem when running Final Cut from a laptop that was dual-monitored, but once you take away the secondary monitor the Final Cut windows remain floating aimlessly out of screen. They were floating off-screen, as I thought, and fixed it with the applescript. While I was working though, I was confused on where the **** the splice tool went. I looked everywhere in the application I could to find it, but it wasn't until I called a friend and he assured me that the tool actually did exist that I remember the teeny-tiny tool panel that would typically reside next to the timeline. The applescript can't pull it for some reason.
So my question, *is there a way in which you can change the display an application starts in?* (bolded for ease of discovery in this long post) what would fixedly open in the main display instead opening to a secondary monitor. Or, as consolation, possibly rescuing that tiny tool panel? Early on I tried keeping a shortcut key set to switch the main monitors back and forth, but found that applications will switch with them, applications I didn't want to switch. Plus, the Wacom Pen has to be re-calibrated when the Cintiq is switched to the secondary monitor, and then, of course, re-calibrated again when it's switched back to the main.
Any help would be greatly appreciated. Thank you.

All my Monitors are set to their native resolutions, 1280x800 is Final Cut's suggested optimal resolution. My Cintiq is a Tablet Monitor, one that allows you to write or draw upon the screen itself, as such, it's set upon an adjustable stand that will let you place the Tablet Monitor upright, semi-flat against the desk, or anywhere in-between, in addition to 360 degree rotation in its flat position. This means that the Tablet Monitor comes with two native resolutions, one for Landscape and one for Portrait. The Cintiq is purposely designed to allow it to be set in a Portrait position, for the comfort of the User. 1200x1600 is just as native for the Cintiq as 1600x1200. Also, my Office Desktop set-up is, God-willing, a permanent set-up; I don't disconnect Monitors, and they are set to Extended Desktop Mode.
My aim was to avoid switching back or forth between resolutions or Mirroring. This will work, yes, but having to do it every time I need to use Final Cut, or any other such program with odd monitor requirements, is a hassle. With all the various windows and applications I have running at any one time, I'll be wasting time moving and resizing windows across multiple Spaces back to where they were every time I need to run Final Cut, and re-calibrating the pen to the new resolution. Which is also a little embarrassing when I need to demo a clip for my bosses and co-workers and I have to spend time, in which I could be explaining things, tiding up my desktops. It would be ideal to have it prepared before they got there, (actually, ideal would be not having to prep it in the first place) but not all meetings are scheduled and planned.
As for windows that get lost in space, that's what the Applescript was for, but apparently that little tool panel, which is wholly more important than it's size suggests, doesn't register as a window and gets left behind.
So my hoped for solution is a way in which to force a Program that would normally load onto the Main Monitor to instead load on to a chosen Secondary Monitor, one that fills the necessary resolution requirements of said Program. I couldn't care less about the Applications need for the Main Toolbar since I run Secondbar anyhow.
This isn't a vital emergency though, I'm just trying to find a solution for an annoyance and to make the whole process more efficient. Oh well, C'est la vie.
Thank you for your reply Dennis.

Is there a way to place the Dock on the bottom of a secondary monitor?

I use my iMac as primary monitor and a secondary display on the right. Is there a way to place the dock on the bottom of the secondary monitor(in a way that the display arrangment actually match the monitor position on my desk)?
I want something like this, with the red marker as the dock(the display arrangment match how the monitors are in my desk):
The solution I'm working with is:
I could turn the monitor attached to the iMac as primary(and set the dock there), but I got some problems with programs opening in wrong positions all the time and some issues with full screen programs as well(also I think the iMac didn't handle well setting the primary display in another monitor).
If there isn't a way to do it in Mountain Lion, will Maverick do any better?

Don't know of a way to get the Dock on the top.
But, to keep it out of the way but available, in the Dock prefs pane in System Preferences you can set it to "automatically hide and show". Choosing that setting means the Dock will normally be hidden; to gain access to it, all you need do is brush the bottom of the screen (or the side you have Doc set to) with the cursor, and it will appear, staying visible only until you move the cursor away.
You can also use the keyboard combo Command-Option-D to invoke/revoke Dock Hiding, which in effect means you can use that keyboard command to toggle the Dock's visibility.

Detect displays seems to have quit working? The secondary monitor is bleeding into the MacBook Pro monitor. How can I fix this?

I am using a MacBook Pro 2009, Snow Leopard (OSX 10.6.8). All of a sudden last night after a long day of work, my monitor resolution changed without warning and the secondary monitor display started bleeding into my laptop monitor. When I go to detect displays, it doesn't fix the problem. It looks like I need to switch to a larger display setting and the largest setting has disappeared.(The display seems to default to this setting where my screen bleeds into the laptop monitor.) When this started happening last night, I immediately shutdown and restarted to see if this would fix the problem. So far, it's still not looking too good.
I also tried shutting the laptop and using the external monitor only. When I do this, the monitor freaks out and keeps flashing on long enough for me to input a password. Then it flashes off, the computer and dipslay goes to sleep and I have to re enter my password to exit sleep mode and the process starts all over again.
Here are screen shots of the two monitors side by side:
http://danisco.files.wordpress.com/2013/07/monitors.png
(Notice the weird overlap - it's not keeping me from working, but it's super annoying!)
Any ideas on how I can try and fix this? OR do I need to get help from Apple directly. Thank you in advance for any suggestions on this!

Okay - this issue seems to have resolved on it's own. Yea!
I did find a thread that suggested resetting the PRAM/NVRAM so I did this, restored the external monitor to factory settings and went into Disk Utility and repaired disk permissions and verified disk permissions.
Here is a link to reset the PRAM/NVRAM: http://support.apple.com/kb/HT1379
These things may have helped resolve this issue. I can't tell what worked because it was hours after I did all these things that my monitor and computer decided they liked each other again. If you have a similar issue, maybe these steps will help you resolve your problem too.
Hope this is helpful!

My secondary monitor flashes and blacks out after the 10.7 install. Any ideas on how to fix this?

I have installed 10.7 and the secondary monitor flashes and blacks out. I downgraded back to 10.6 and the problem went away. I reinstalled 10.7 and the same problem happened again. The monitor blacks in and out especially when the pointer is placed in the dock area, but it still happens all the time. My secondary monitor is a ViewSonic 22 inch that is connected to a DVI to display adapter. Any solutions??
Thanks

Talked to AppleCare and it's most likely the fact that my MacBook has 3.0 USB ports and my non official charging cable can't support that. So yeah, I'll try a new cable, hopefully that's the fix.

How to use a secondary monitor in Portrait mode

Finally discovered how to do this. Here is how to use a second monitor in portrait mode:
Open System Preferences from your iMac dock.
Click Displays - Click Arrangement - Click Gather Windows - the secondary monitor dialog box opens.
Click Rotation - Click 90 degrees rotation for PORTRAIT MODE.
Click CONFIRM on the secondary monitor to keep Portrait mode.
Select the desired resolution. I chose 1200 x 1920.
You'll see a dialog box that says, "About to change the display mode."
Click OKAY.
Click Confirm. (If it appears. For some resolutions, I did not have to click confirm, most likely because the monitor supports those resolutions.)
Then resize the windows of the software you're using.
Done!

I too got the same. Both monitors went portrait. Then I unchecked the 'Mirror Display' option in the Arrangment tab of iMac display and voila. Got what I wanted.

Windows gets rearranged in Windows 8.1 and secondary monitor when computer goes to sleep

I have a MacBook Air 2013 with a secondary monitor installed through a mini-display port-HDMI cable. I also have bootcamp installed in Windows 8.1 64 bits with all the latest drivers installed. The problem that I have is that when the computer wakes after it goes to sleep, all the windows in the non-primary monitor moves to the primary monitor and I have to re-arranged them all over every time.
What I tried so far:
1. Installed the latests drivers from Microsoft and Intel HD Graphics 5000.
2. Look for the DMMEnableDDCPolling in the registry. (not found only available for ATI cards)
3. Change the mini-displayport-HDMI cable for a new one that doesn't transmit the "power" so that computer do not detect that the monitor was shutdown.
4. Change the resolution on boths monitors to native resolution
5. Change the primary display from external monitor to laptop monitor
6. Changer HKLM\Software\Microsoft\TMM\UseIViewHelper from 1 to 0
7. Try to get an answer from Apple, Intel and microsoft support.

PLEASE HELP! I Don't know what else to do!
This do not happend on MacOS, is happends only in Windows.
Thanks, Andres Rormoser.

The only solution that I found so far was to install Actual Window Manager, separate the secondary monitor in tiles, assign each window to each tile, add a shortcut to start/stop ActualWindowManager and every time the computer wakes up with the windows re-arranged I press the shoutcut and everything goes back to my predifined layout.
