Query: This product causes more problems than it does good...

I bought this program, and I stopped using it within 2 months... why?This program, at least for me, tends to bug a lot, and it does a lot of screwy things that you never intended. For example, notes that I never entered in appeared towards the end of my pieces, and there was no way that I could delete them.Also, it would randomly bug at some times, and I would have to quit the program, losing everything that I worked hard on (wouldn't you all be frusterated if that happened?).Also, and it may be because I didn't figure it out entirely, I couldn't have two different note heads on the same beat (example, half note and quarter note on beat one) on the same staff. It just wouldn't work.I would strongly consider buying another notation program. I use Cakewalk Scorewriter, which is about as cheap as this, and I hope someday to get Sibelius... when I have the money to do so (...)
