3000S clutch 'snatch'

[duncscz]

Was having trouble with the clutch at low speeds in traffic - quite some 'snatch' as the clutch bit - difficult to start moving smoothly. Clutch etc replaced etc and things improved considerably, but now find that when the engine is hot, the clutch again becomes more difficult to use in traffic.
No problem getting into or changing gear though. Previously replaced clutch cable and greased it up.

Seems such a simple arrangement, I'm not sure what else to check ? Could it be the pedal box alignment ?
