EXS 24 Logic Sampler Users Group

Hi there,
Since like 4.7 or so I don't seem to be able to edit a sample from the 
sample edit window as fine of increments as I once could. 
Some of the samples I haveTranslated from the Kurzweil format have loop 
points that are finer than I am able to access using the sample edit 
window. When I try adjusting them the loop point jumps to a larger 
selection that is un usable. I tried changing view from bar/beats /samples 
etc.... but that doesn't seem to do the trick.
Any help would be greatly appreciated!
