Blender Version

Short description of error
Trying to change opacity value does not work in properties panel.
Showed it to hjaarnio and JA12 on IRC, they've advised to report bug

Exact steps for others to reproduce the error
open file, change opacity on the properties panel to anything other than 1.0
changing the preview window to something else seems to solve the problem!

Don't know whether it's a bug, but it's reproducable back to (at least) Blender 2.57b on win7/64

Addition: The problem disappears as soon as you switch the top-right window type from VSE to 3D view (or any other window type).

Addition #2: You can keep the VSE window but change the "proxy render size" from "no proxy, full render" to "no display". This also "solves" the problem.

Yes, it’s a very old known issue (related to dependency graph iirc), so considered a TODO. Thanks for the report anyway. :)
