I am using version 2.4.1107.12, and I am able to split one file successfully, but then the program stops responding. It doesn't matter what format the file is (wmv, avi, mp4, etc...); I have one successful split, then the program doesn't respond, and I have to force the program to close, and restart it to do another split. Anyone else having this problem, or any ideas as to why this is occurring? Thanks.
