Thanks, the change should at least help others. If there is a way to make the help part of the dialog show the whole path (with 2 lines of small font or something) it might eliminate the need to communicate with confused users the need to control-click. (Or, not display the path at all in the help line but have the help line tell you to control-click to see the path).
I had to get my CD out for Christmas. So, my solutions had to use your software "as it is". I relocated my images so that the path is short enough to be completely displayed by your program. And then I updated the path for each slide (over 400) with your program, manually-- about a 3 hour job. (I was really glad that I had first created the slideshows with iPhoto and could check my ESSC sequences when finished.)
