Bugs in Wavelab 8.0

Hi Guys.
I’ve been using Wavelab 8.0 since 2013. The point is that there are some bugs that are complicating my work. Since I use OS X, there are 64-bit third-party plugins that work erratically, specially UA2 Universal audio plug-ins. I use 64 bits Wavelab version. I have installed the latest version of UA drivers. Other porblem, from the begining, in Windos 7 and in Sierra OSX is that when you click to move the master section and then release the mouse button, the master section keep linked to the mouse. I’ve never solved what causes this bug. I want to know if someone has the same problems, and if there’s a way to fix it.

Waiting for a solution. Thanks, and Greetings
