This is very frustrating, and I've posted about this before. Certain mouse movements / commands simply don't work on Logmein but they work fine on TeamViewer (so I know it's possible).
I experice this on adobe products, mostly on Premeire. I can't drag "rubber bands" as they are called and this makes it impossible to do certain things (like time remapping). I have to use TeamViewer to move the rubberbands, and Logmein to hear the audio -- insane.
Please look into this, there are a lot of people using Logmein for remote video edting.
