Hi,
If you have say 0.2 of a second to cut the in/out points will be to close. What you can do is insert a section of silence. Say you insert 1 second of silence, now reset your in/out points for 1.2 seconds. The in/outs should now be long enough to make the edit. You remove the 1 sec of silence and also the 0.2 sec of material you wanted to cut.
Alternately, export the file to a PC and edit using software.
