Screen Capture: Part Of Selected Area Only Options

[DavidHS]

I select a large area of the screen to capture but the area actually captured is smaller than my selection. The actual image size captured varies around 1300 x 900 pixels.

This is on running PMView Pro 3.51 with Vista SP1.
My display resolution is 1920 x 1200.

Is there some subtle Vista or PMView limit at work here?

A possible factor: This PC is a laptop with a native resolution of 1400 x 1050 but displaying onto a larger external screen. The video card and driver are well capable of running this screen at the full 1920 x 1200. I have rebooted (a number of times) since starting to use this larger screen.

I note also that IrfanView exhibits similar behaviour, although the size captured seems to be slightly smaller.

So, do we have some Vista issue here?
