[Solved] How to remove a transparent window on the desktop

I am using KDE 4.5.3-1.
$uname -a
Linux desktop 2.6.35-ARCH #1 SMP PREEMPT Sat Oct 30 21:22:26 CEST 2010 x86_64 Intel(R) Core(TM)2 Duo CPU E7200 @ 2.53GHz GenuineIntel GNU/Linux
There appears to be a transparent window on my desktop, as shown by the shadow outline in this snapshot:
http://individual.utoronto.ca/davidshih … pshot.jpeg
It appears with different wallpapers, and I can't seem to disable it. Right-clicking brings up the same context menu as outside the ghost window. Nothing in Desktop settings appear to control the appearance of this window. Restarting does not help.
I am not sure when it appeared...

How do I stop my MacBook removing all my icons from the desktop ?

How do I stop my MacBook removing all my icons from the desktop ?

Hi Matt
After I create say a word document, file it on my desktop and then shut down my machine. The next time I open up the MacBook the file icon has been removed from the desktop. I can still retrieve the file in a folder labeled with the month I created it. But why has the OS removed it from the desktop and how can I stop it happening?
It happens to alias icons as well!

How to remove my credit card from the App Store

How to remove my credit card from the App Store

I used a pre-loaded credit card so when it ran out i had problems, primarily because it wont let me download or update anything until the "billing problem with the last transaction" was resolved. I dont really care if the purchase goes through but i want to be able to update stuff again and it wont give me the option to select 'none' under payment type. do i have to put another card on there just so i can "resolve the billing problem" and then i have to take it off again or is there a way around this or is it a never ending cycle?

HT1343 how do I switch between windows in the same programme? I know that I can use Command tab, however this takes you through all of the programmes that I'm using. What I need to do is have a shortcut to switch between windows in the same programme.

how do I switch between windows in the same programme? I know that I can use Command tab, however this takes you through all of the programmes that I'm using. What I need to do is have a shortcut to switch between windows in the same programme. For example if I'm in Excel and have 5 windows open I want to be able to scroll between each window of Excel only with a shortcut.
Please help!

Command and ~ keys to tab between open windows.
Technically it is the Grave Accent ` (aka reverse quote) under the tilda ~ key. Tilda ~ is shifted, and Grave Accent ` is not.
Command-Grave Accent

In idvd i do not see a window but hear the audio, how do I get a window on the screen?

In IDVD id do not see a window but hear the audio for a new project. How do I get a window on the screen?

You need first to import a movie of your own, fill drop zones with your pictures, etc. The audio you are hearing is just the built in preset. Take a look at: http://www.apple.com/findouthow/movies/idvd.html

Blinking Windows on the Desktop

Computer Dell Vostro 1510 with 2 GB RAM
Operating System: Windows XP with all service packs and updates
Recently I installed/updated Firefox to the latest beta version. That went well. The following day, I booted the laptop and windows on the desktop blinked in and out and shrank in size. If I double clicked on the shrunken window it would open and I could do some input. As long as the mouse pointer was on that window I was fine. If the pointer strayed away from that window or I had to go to another open window, the the blinking and shrinking would re-start.
I did check for viruses and malware and none were found. I have had this happen in the past with another beta version of FireFox and the only solution was to remove it. Firefox was never opened during the sessions.

That's very strange. If you check the Task Manager (Ctrl+Shift+Esc > Processes tab), if Firefox.exe running invisibly? If not, it's hard to see how Firefox is involved. ???

How can I use applet to get the desktop image of client

hi,I have a question to ask u.
How can I use applet to get the desktop image of client? Now I develop a web application and want user in the client to get his current image of the screen.And then save as a picture of jpeg format ,then upload it to the server?
I have done an application to get the screen image and do upload file to server in a servlet with the http protocal.

Since the desktop image is on the client's local hard drive, you'll need to look at trusted applets first.

How do I CREATE A SHORTCUT ON THE DESKTOP?

New to the Apple family. Always have been a PC person. Just got fed up.. Would like to find out how to cut and paste with the mouse and also my main question is not knowing how to set up a shortcut on the Desktop for faster internet access to certain specified sites.... Thank you for any help you may be able to provide. I signed up for one on one training.... I hope it wasn't a waste of money.
Make it a great week,
JO

Hi there
This post may be under the wrong section, if you are a new Mac user, then you most likely have an Intel based Mac, not a PPC. And also, you may want to not write IN CAPS as it usually indicates yelling in a forum environment
1. You cannot Cut & Paste on a Mac, you may Copy & Paste, if you want to Cut & Paste (CMD + X) you can download MoveAddict from the Mac App Store.
2. EDIT: Sorry, I thought you meant Application shortcut - do what he said \/ \/ \/
Hope that helps

HT2491 how to show macintosh hard drive on the desktop

how to show macintosh hard drive on the desktop in apple macbook pro,n how can i install my canon scaner with printer on mac,i am new user,regards,dr.m.imran

Thank you for these directions. I just created a new user account and couldn't believe the hard drive was not viewable on the desktop. It seems by default the hard drive should always be viewable on the desktop. By having absolutely nothing on the desktop when making a new user I was freaking out thinking my Mac had a bug after the OS updates.
Thank you for the directions on how to show the hard drive on a new user's desktop.

[Solved] How to list recently used windows?

I like the Unity feature where a key binding either opens or focuses an application window. With KDE I can define a keyboard shortcut which, for example, performs
wmctrl -xa emacs.Emacs || emacs
However, I'd like it to focus on the last focused window, not the first opened window. Is there a command to list all windows in the order they were recently used? (Clearly the Task Switcher gets this information from somewhere.)
Last edited by raul_l (2014-12-16 16:58:24)

The command I was looking for is
xprop -root | grep "^_NET_CLIENT_LIST_STACKING"
If anyone is interested, this script
#!/bin/bash
app=$1
workspace=$(wmctrl -d | grep '\*' | cut -d ' ' -f1)
win_list=$(wmctrl -lx | grep $app | grep " $workspace " | awk '{print $1}')
IDs=$(xprop -root|grep "^_NET_CLIENT_LIST_STACKING" | tr "," " ")
IDs=(${IDs##*#})
for (( idx=${#IDs[@]}-1 ; idx>=0 ; idx-- )) ; do
for i in $win_list; do
if [ $((i)) = $((IDs[idx])) ]; then
wmctrl -ia $i
exit 0
fi
done
done
exit 1
in conjunction with the key binding
the_above_script.sh emacs.Emacs || emacs
produces the correct Unity behavior. (How to mark this thread solved?)
EDIT: I modified the script a little bit. It turns out wmctrl and xprop use slightly different formats for displaying hexadecimal numbers.

Remove "Java Applet Window" from the window

Hi, can anyone tell me how to remove the word "Java Applet Window" from a applet/frame/dialog running on the browser? Thank you very much.
yunhe

You have to sign your applet. Make a search on how to do that. It's not that easy and you need a certificate.
