I don't seem to be able to set a Solid Color Transparency from the Preferences Panel.
I go for black (that's the color I want) then every time I reboot the application it automatically switches to solid white.
Any idea why does happen?
Forgot to mention… I'm running v.0.5.1 on a MacBook intel Tiger.
Good catch, that does appear to be broken in v0.5.1. I logged a bug on it.
The bug is fixed in the latest revision so it's just waiting for the next release. Thanks.
