Knowing when popup opened

In win32 programming when you open a modal dialog/popup the
underlying application does not recieve any ui-related messages, but not so in flex..
I have a problem with a custom uiComponent that hides/changes the mouse cursor when the cursor goes over it.
It still occurs when a modal dialog is open so I need to know the best way to handle disabling this behaviour when a popup is open.
I could not see a function to tell if any popups are currently open.
Andrew

ok then thanks.
The mouse behaviour is non-standard - it is receiving stage mouse move events because there is a bug in windows meaning I don't get local mouse move events when mouseX is equal to 0 which I require (bug has been submitted).

Newbie - How can I know when someone opens a PDF I sent in an email?

I'm trying to get a simple proof of receipt when someone opens a PDF attached to an email. Any suggestions about how to do this?

Thanks try67. Consider this: I'm not trying to silently trick the receiver, either. I intend to explain to them up front that when they open the attached PDF, it will provide a signal that is the proof they have been notified. It's also okay if this isn't easy; I have IT people that can do it.

Does a sender know when I open an email?

I already have Thunderbird set up to put spam in the spam folder, but occasionally it puts a wanted email into spam, so I always have to check through the spam folder. Recently I have started getting an absolute avalanche (at least a dozen a day) of particularly obscene spam advertising how I can get any young girl laid whether she likes it or not. I am 80, and rather past this kind of high jinks! They come from a wide variety of senders (or I suspect one sender but a wide variety of addresses) so it's difficult to block the senders. My first question is: If I open them to delete them, does the sender know I've opened them, and uses that information to send more, or is there no such feedback? I know I can delete them one by one without opening by right clicking and selecting delete, or I can select them all and press delete, but then I've opened them all. I can't disable the message pane because in version 31.2.0 under "view" there is no "layout>message pane". So if the answer to my first question is "yes" how can I delete a block of messages without opening them?

Thunderbird does not run code in their message viewing so unless you click a link it is high improbable that you are going to send any kind of message acknowledgement back to the spammer.
FYI: The Message Pane choice is hidden under Options-Layout in the new and not improved menu system.
The shortcut of F8 still works just fine to toggle the message pane on and off.

You installed the Conduit spyware. To remove it, triple-click the following line of text to select it:
~/Library/Application Support/Conduit
Copy (command-C) the text to the Clipboard. Then select
Go ▹ Go to Folder
from the Finder menu bar and paste (command-V) into the box that opens. A Finder window may open with a folder named "Conduit" selected. If so, delete the selected folder.
Select Go to Folder again and enter:
/Library
From the folder that opens, delete the following items, if they exist. You may be prompted for your login password.
Application Support/Conduit
InputManagers/CTLoader
LaunchAgents/com.conduit.loader.agent.plist
ScriptingAdditions/ct_scripting.osax
Close the folder. Now select Go to Folder one more time and enter:
/Applications/Toolbars
Delete that item. Close the Finder windows you opened. Log out and log back in.

Not a virus, but it is malware: The Safe Mac » Search Results » adware removal.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

Hey jeroenb16613921,
Please specify exactly when you get this white popup screen. While opening a PDF or launching Acrobat by double-clicking on the Acrobat icon.
If it comes when opening a PDF, then where is this PDF actually stored?
Let me know more on the same so that I can analyze the issue.

What does "you have data to Sync, go to TOC and press Sync" mean when I open the Bible 1 App. I don't know what "TOC" is

When I open my Bible +1 App the following appears - extremely too brief to read once - "you have data to Sync, go to TOC and press Sync.." on my iPad. I don't know what TOC is, or where to go to Sync my data. I also don't know WHAT data I have TO Sync. Also, is there an Instruction "manual" so-to-speak that explains more about the latest update from November 27? I'm working off an iPad 2 which is my ONLY piece of computer "anything" so all I'm woking on is my iPad. I also do not have access to any person's lap top or computer. Can you help me?

Went to Google, tonefox, and found the information. As I told Meg, I am still "way over my head" with computers and still have to remember that you can 'Google" pretty much ANYTHING.

Does any one know what the matrix.dms is? And why it is in my picture folder? When I open this file the unarchiver takes over and I see my entire hard drive when I scroll down I see the matrix.dms file with in the unarchiver.

Hello everyone. Does anyone know that the matrix.dms file is? And why it may have came to be in my picture folder? When I opened the file the unarchiver took over, then I saw my files in the unarchiver window. I then scrolled down and I saw the same matrix.dms file within the unarchiver window. I made a video of what saw when I tried to open the file, so as to aide in your understanding of reason for my perplexion at this file.

Hello! I used QuickTime for watch any videos on OS X Mountain Lion, but now, I'm passed to OS X Mavericks and QuickTime, when I open an .avi file, convert this in a .mov file. I'm sorry for my English, I'm French and I don't know speak English very well,

Hello! I used QuickTime for watch any videos on OS X Mountain Lion, but now, I'm passed to OS X Mavericks and QuickTime, when I open an .avi file, convert this in a .mov file. I'm sorry for my English, I'm French and I don't know speak English very well, but what can I do for QuickTime opens on .avi and doesn't convert to .mov?

HI GalaxieMusique,
I'm french too, but I'm going to write this post in english so that everyone may understand it
I have the same problem in Mavericks, but I'd say, more important, with QuickLook.
Indeed Quicklook can't read avi movies anymore. Actually it always been the case, but with Perian we were able to fix it. The problem is that Perian is no longer available for Mac OS 10.9....
I'd assume that our only hope is Apple themselves... It would be nice from Apple to creat an add-on for quicklook to be able to preview the avi movies.
In regards with quicktime, you can download QuickTime 7 here:
http://www.01net.com/telecharger/windows/Multimedia/lecteurs_video_dvd/fiches/10 0.html
and ask all the .avi movies to be played by QuickTime 7 and not QuickTime X (included into Mac OS).
Sorry for the english, we french people can make mistakes sometimes
If anyone has a solution for QuickLook, please do not hesitate. This topic is becoming a real mess....

Firefox add-ons take some memory. This amount varies depending on the add-on.
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
Does this decrease the memory usage? Please report back soon.
