MATLAB: Do I experience difficulties previewing images with resolutions greater than 640×480 with the Image Acquisition Toolbox

I am using a Data Translation DT3157 frame grabber board with the Image Acquisition Toolbox 1.1 (R13SP1) on a MS Windows 2000 computer. I have installed the latest driver for the board (v2.5 including SDK).
The problem is that when I acquire frames with more than 640×480 pixels only the first 640×480 pixels show correctly. The rest are either old data or duplication of the first pixels again.
I do not have this problem if I use the DT-acquire software included with the frame grabber.

This bug has been fixed for Release 14 (R14). For previous releases, read below for any possible workarounds:
This is a bug in the Image Acquisition Toolbox 1.1 (R13SP1) in the way that it handles previews of larger than 640x480 from a Data Translation DT3157 frame grabber.
To work around this issue, only acquire at 640x480 or fewer pixels.
