Lanes seem to have different "issues" for each user.
I frequently can't slip edit or apply fades.
Close project, re-open project generally "fixes" it.
One of the reasons I feel X2a is just not "ready for prime time".
I'm using it for my projects, but NO WAY would I use it for a paid project; yet.
X1d Expanded on Win 7 x64 is a "mature" and robust platform, X2 will get there.
