yes, while bleeding the slave, many times...

it could be a number of things really. just check EVERYTHING. same exact thing happened to my car. i replaced master and slave cylinder. it wasnt untill i took the tranny off that i noticed my clutch was done.

I had the exact same problem about 2 years ago. turned out my fork was sticking what i put the clutch in so when i pressed the pedal everything looked right but for the first 3/4in the fork wasnt even contacting the pressure plate. so what i did was pushed the fork against the pressure plate and held it there while i beld the slave out. a vaccuum bleeder works great for this. after i did that i havnt had a problem since.

I had the same problem, and it was my pressure plate... RPS Max Street. They warrantied it after about a month of hassle. With my pedal adjusted to no free play the car wouldn't fully let go either. It worked correctly for ~1000 miles while I was breaking it in, and slowly got worse.

i pushed it toward the rear, so that the fork part presses the throwout bearing up against the pressure plate.

Your clutch was done due to being partially engaged while standing still, I.E. constantly slipping against the flywheel.
