Hello, I am using the student version of SW 2014-15. Recently, I found some strange issues with mate. For example, a linear slider moves when I used the mouse to slide it across the screen. However, after I imported it to another assembly, it stopped moving even it is set to flexible. For more details, refer to the thread: Clarifications about constraints please

Are there bugs with mate in this version? I know a newer student version came out earlier this summer. Don't know if my problems will disappear in this version. I am not sure if I should spend my money to buy it. Definitely I am interested in the 2016 version which will be released next summer. Any suggestion?
