Hi!
I just downloaded the Action! 1.4.0 and I cannot record anything in my native 27" screen resolution of 2560x1440. Not even desktop. Action! does appear to be recording something, and the saved video does have a correct thumbnail picture, but trying to preview a video file crashes the built-in player and exporting will only produce blank green video file.
If i set the recording resolution to 1080p Action! everything is working great.
Running on W7 Pro 64-bit + latest updates, Ati Catalyst 12.4 drivers.
Relevant machine specs are:
MB: Asus p8p67 pro
CPU: i5-2500k @ 4.2GHz
MEM: 8GB
GPU: ASUS HD6950 2GB DCU II
DISPLAY: Fujitsu 27" screen with native resolution of 2560x1440 connected to displayport.
