I must say that elevation caching and the features that it enables are very cool.
Since I broke my arm on my last (duh!) ride 2 days ago I have been playing with TF a bit ("virtual riding") and have run into a few things.
For example, I created a track consisting of two points with the intention of filling it in by "adding" points using the spline function. The result was intended to provide a nice cross-section along the line between the start and end. However when I right click on the initial 2 point track, and select "simplify/split/spline track" TF crashes with the error message "Run time error '380' Invalid property value"
The crash is avoided if I add a single mid point using the "select point" / Insert key method.
So now I have a 3 point straight line track that I want to fill with a bunch of other points to be able to show a profile other than a single stair step. There seem to be no settings of the "interpolate" function which will add points to this simple linear track.
Also, twice now I have run into a scenario while drawing a track where the draw tool seems to become stuck in "drag" mode, as if the left mouse button were being held down when it is not. I am not quite sure what steps are required to reproduce this behavior, although I also note that the wonderful "e" key shortcut for removing the last segment was not working just before that happened. However when TF was closed and restarted the track drawing returned to normal.
