Basically, the software works surprisingly well, and after some training you can properly and productively work with. Unfortunately, the work flow is blocked now and then, because the software is suddenly preoccupied with himself and no response any longer. Eventually it comes suddenly on. Real crashes there is fortunately (almost) never. The problem with the looong pauses or hangers I had initially in a Core2duo and therefore specially upgraded to a more powerful PC (Core i5, 8GB of RAM, SSD, Win 7 Pro 64 bit), but much better, it was not this also. Again and again "hooked" it here and there.
For those who can tap not as good and fast and have a bit of patience to deal with technical tasks and problems, the software is despite its shortcomings but a big help, especially when you compare it with frequently recurring words and phrases has to do.
