Issue deleting pictures

I am having trouble deleting pictures when I am in pictures library section (call it what you want) only. Pictures inside the documents or any other place delete after i select yes to delete this picture and it will be sent to recycle bin etc etc.

The main issue lies inside the picture library and in the fact that after i have said yes to delete a picture it simply doesn't do it until i leave the folder and enter it again and then its finally gone. I got quite a lot of pictures of cars and i need to get rid of the junk ones so but so far I haven't been able to do because of this problem.

I am not sure if i have done anything wrong, so if anyone has an idea help.

**It happens in folders with bigger chunks of photos, i tired it with 5-6 and it deletes after i say so. Probally after 100 pictures it seems to not delete after i select it. **

Oh dam i refreshed my page while i was typing.
To make it quick.
1. Got home and wasn't annoyed so i logged on to try and read your message and i went to try once again.
2. Pictures still failed to be deleted and be refreshed. So went to my Nvidia Control Panel to change the refresh rate from 59 to 60 instead.
3. Not sure if what i did had any effect since it went up only +1. Still to no avail nothing worked
4. I right clicked on the properties for some reason thanks to Harpua and i looked at it and i noticed there was an additional option. It said [clear changes].
5. I click and tons of pictures delete (i forgot to say i use some image duplicate finder) and then tried deleting another picture and it worked.

I am not sure if it was the image duplicate finder program, the refresh rate or nvidia, but everything worked by dumb luck and thanks to harpua for giving me better description for myself and anyone else who might happen too.

can you be more specific on what 'properties' you right clicked on? i too am having no luck deleting pictures frome the wmp12.....tia....

Well to be more precise, i just right clicked on a blank spot between images. and the option to clear changes was there. I am still trying to duplicate my issue. I don't think this has to do with wmp12 and its another reason i dont use that. Sorry i cant help with that

Down below is a picture, but without what i actually saw.

i have no problem deleting them there, the problem i have is after deleting them there and in their original folder i see empty frames with the old titles still there in wmp12. i have shut it down and am now using nero 8. i guess i will have to not have wmp12 and media player on my 400.00 software that refuses to let you manipulate files unless you know the "secret".

well i finally was able to delete the empty titled frames doing what is below. if you get err saying wmp is in use do a ctrl/alt/del and end the wmp process and do as shown below.....



clear the Windows Media Player database. To do this, follow these steps:

1. Exit Windows Media Player.
2. For Windows XP:
   
   Click Start, click Run, type %userprofile%\Local Settings\Application Data\Microsoft\Media Player, and then click OK.
   
   For Windows Vista:
   
   Click Start, click Run, type %LOCALAPPDATA%\Microsoft\Media Player, and then click OK.
3. Select all the files in the folder, and then click Delete on the File menu.
   
   Note You do not have to delete the folders that are in this folder.
4. Restart Windows Media Player.
   
   Note Windows Media Player automatically rebuilds the database.
