The same thing happens to me. I am unable to find error file or anything else. It seems related to the Stroke Counter. The last time I set it to 0 it never crashed. Seems like if it is running high (20+) it crashes faster, or low (5) it crashes slower. Hitting the U button doesn't make a difference....

with all versions of CTI somewhere random between 100-250 the timer will just click once on a slide and the entire program will freeze up. happens every time, is there a way to stop this
