"I just checked this on the original X2 (pre X2a) on my Win7 HD and it was broken in that version too. Checked X1 and it works fine there."
Exact, the problem came with X2.
Maybe because of the new "clip header indicators" ?
And i confirm that these peak markers are very useful (to quickly check the levels when recording, setting compressors, etc).
I really miss them.
