FL (VSTi) sync. Not working with Tracktion

[Sidhu]

Using FL as a VSTi. Made a short tune today evening. Guitars in T1, Drums in FL. All ok while composing.

Opend the session now. Start playback. Everything fine. Stop playback. Go to the FL window to tweak a pattern/make new pattern. Select the Pattern playback (not song). Press play in FL. Fl will not play, goes into pause mode. Put FL into stop mode.

Go back to the T1 window, press play, FL not sycing, stays in Stop mode.

Put FL in pause mode (by pressing play in FL) Go to T1 window, press play, FL starts playback, but from FL's current cursor position. Does not follow T's position.

Press Stop in FL twice (goes to start). Take T1 transport to top too.. Put FL in pause (by pressing play in FL). Press play in T1, both applets start playback from top, but FL no longer mantaining sync, total drift by the 3rd bar.

Im getting a little tired of FL never syncing proper to T. What do i do now ? I tried REwire too.. but with rewire FL never gets the tempo right, and defaults to 140.
