Operating system and graphics card
Dell Inspiron 1536 laptop, i5, 4G ram, windows 7-64 bit,
Broken: 2.70 64-bit 19e267c
Worked: 2.69 & down
In the VSE, after maxi/minimizing any window,
blender windows stop updating but audio continues to play. Everytime.
Just load a vid, w or w/o Audio, alt+a, it plays fine, shift+space to maximize any blender window,
the update freezes("anim player" icon goes away), audio will continue to play, alt+a again, and it will start back updating at correct spot.
UPDATE: I just noticed its all windows,3d, clip ed., not just the VSE.
I posted on blenderartist.com but not much help. Thank you for Blender!
