Hello Moose,
Could you please try to use the beta version of Video Splitter available from:
http://solveigmm.com/download/SolveigMM_Video_Splitter_3_7_Beta.exe If the problem remains with this version, could you please upload for us file that you have tried to edit (when it locks up on trimming)?
You can use any file host service, e.g.
filedropper.com or
dropbox.com.
Also please send us the project file. Select fragments for saving then go to
File -> Save project as. You can send this to support(at)solveigmm(dot)com.
Also please record log files. Here is how to get them:
