CS4 (as2.0) - text missing

hi guys,

when i publish an exe from flash on some of my screens the last letter of certain lines dont show the whole text characters for examle somtimes it looks like some of my s is missing or a ‘d’ looks like a ‘c’ becasue the line has gone off the d.

sounds weird but any ideas would be great. its doing my head in!

Cheers in advance
