Notepad problem

Isn't there an easier way of doing this? Opened notepad, box appeared off centre with left of box offscreen as has been the case since problem first occurred. As suggested tried pressing shift then rt click nothing comprehensible appears as a way of fixing it.

Other options didn't understand.

 

Notepad problem

Your press and hold Shift then right click on the Notepad icon in the Taskbar that represents the open Notepad window. Then you use the up/down/right/left arrows to move the window on the Desktop. If the windows is too big then select Size instead of Move then use the arrows to change the size of the Notepad window.

Tried to make a movie demo (first time) but not sure it helps:

MoveNotepadWindow.zip

It's a zip file so oyu need to download it then unzip it. It will be a wmv file that you can play with Windows Media Player.

 

notepad

04sall is the name of the document that Notepad has opened. Usually Notepad is meant to open "text" or "source code" files, however it can open other types of files. Now relating back to your issue, the fact that 04sall does not have file format means
that it used by a program or Windows, and could be quite large. This might have caused Notepad to freeze. You will have to force close Notepad, to do that please follow the following steps.

Step 1: Press the buttons "Ctrl, alt, and delete" simultaneously. A list of options should come up. Click on Task Manager from the options that display. Note, if Task Manager is unable to open OR pressing the buttons "Ctrl, alt, and delete" simultaneously
does not do anything, jump to Step 5.

Step 2: In task manager select Notepad. Now click the "End Task" button. If a confirmation message comes up, then click "End Task" in the confirmation message. If Notepad closes then problem is solved. If Notepad does not close please repeat this step.
If repeating this step after 5 times does not work, go on to Step 3.

Step 3: Select Notepad on task manager, right click on the selected Notepad in Task Manager. A drop down menu should come up. Select "Go to Details". After doing this DO NOT click on anything yet. Go to step 4.

Step 4: There should already be something highlighted, right click the highlighted object, a drop down menu should appear. Click "End Task" option from that menu. A prompt will come up, click the "End Process" option on the prompt. If Notepad closes then
problem is solved. If Notepad does not close, please repeat this step. If repeating this step does not work, got to step 5.

Step 5: Hard shutdown the computer, by pressing onto the power button. DO NOT LET GO OF the power button until the computer power indication sign has turned off. Now turn the computer back on. If the issue is gone, then problem is fixed. If "04sall-notepad"
opens up again on startup, please reply back stating that.
