I've used MTC for over 4 years now and recently it has been really buggy. I have problems with it crashing when welding or splitting. It isn't consistent, but it is pretty constant. Sometimes it will happen 20+ times in an hour. I have to save between each change just so that I don't lose any work. If I have three words in the same font, that need to be split and then welded together because of the cursive letters, one of them will work fine and the the other two crash. Other times it is the other way around. I have found that shrinking them to less than an inch tall usually helps, but not always. I have also had problems with a C++ runtime error as well. Can you tell me if this is because I have Windows 10 or are there other problems that are being fixed?
