Script or action to make last opened document the active document

[jim_blandford]

I have an action which resizes and sharpens an image. It then runs a script which imports the layers from another open document (Watermark1600.psd)

After the script has run, the active document is always Watermark1600.psd, however I want it to be the last opened or previously active image (i.e. the image that has just been resized, sharpened and had the layers imported.)

I have Googled using a few connotations searching for what I want, to no avail.

Any help appreciated, thank you.

In the script, do the first command.

var act_doc = app.activeDocumnet;

The last

app.activeDocument = act_doc;
