Need help. something is either wrong with my photoshop or camera

[ipod]

hello to all of ya. i need help. i only discovered the below problem recently.

i'm using cs 3, d90. the problem is that when i use my cs3 to open my pic, in preview mode (before i select the picture), i see line on my pictures taken in potrait style (name of picture attached: photoshop showing lines)

however if i change to os dialog the line disappeared (name of pictured attached: line disappears in os dialog and line disappears in os dialog2)

also, i can still open the pictures in cs3 (those with lines) and it looks fine (line are not there at all).

Do you guys ever encounter this problem? is there anything wrong with my d90 or are all my pictures corrupted?

Not a problem i encounter in pshop but in other apps it can be the % sizing in the preview pane. try adjusting the size of your preview thumbs. You will probably find the line disappears in them too. It can happen when the image is not at a constrained ratio of the original picture.

Does it show up in your images?

If not: ignore it.
If so: you've got an issue. Re-install the software.
