System Information
Windows 7 Professional; Installed Memory: 4.00 GB; System Type: 64-bit Operating System; Computer: ACPI x64-based PC; Processors or Graphics Card Info: I believe I have 2 Intel Core 2 Duo CPUs P8700 @ 2.53GHz

Blender Version
Broken: Blender 2.69.7 Hash: 41e70cf and also the official release, Blender 2.69.0 r60995
Bug should occur again when I use any version or build of Blender on THIS SPECIFIC SYSTEM.

Short description of error (SPECIFICALLY FOR MY SYSTEM)
In a basic scene in Blender, I open up the video sequence editor. I then add in either an image, movie, clip, or scene into the sequencer. When at least one of those items is added onto the sequencer, the image preview window won't show the image of the frame number the playhead is on. Instead it is replaced with a pale, white image. The only way to preview the image of the frame number is if I render that frame number out into an image by hitting F12. I'm not sure if this is a bug, or if it's because of my system or my graphics card. I was able to preview the image frames fine on another computer system (Windows XP) but how come not on this one. WHY?

Exact steps for others to reproduce the error (SPECIFICALLY ON MY SYSTEM)
Open up a basic scene in Blender. Go into the video sequence editor. Go to Add>Image, Add>Movie, Add>Clip, or Add>Scene or add one of those items in by hitting Shift+A. When added into the sequencer, the image preview window of each frame should be revealed as a pale, white image. .blend files and .zip of the screenshots of this bug are available to download.

This typically means that your graphics card does not support non-power-of-two textures, which is an OpenGL feature we rely on here. You can try updating your graphics drivers to the latest version (go to the Intel, NVidia or AMD website depending on your graphics card, Windows update may not automatically give you the latest version).

Your report does not mention which graphics card (GPU) you have, only the CPU, so we can't tell if it's supposed to work on this system. If updating graphics drivers does not work you can attach the output of Help > System Info (this will create a text file in Blender's text editor that you can save), this will give us information about your graphics card and which OpenGL features it supports.

It appears you do not have any OpenGL driver for your graphics card installed, just the default Windows OpenGL driver which is too old to work well with Blender.

I can't tell which graphics card you have from the information, but here is some general instructions on how to update graphics drivers, you can find other guides searching Google.

Further there doesn't seem to be any bug here, only solution is to install a new driver and if that's doesn't help, this card is simply not supported by Blender.
