I have been fighting with Solidworks for almost 2 years now. I have been a customer since 2005. Every year it gets worse and since the update to 2019 I have had so many problems. 

1. Assemblies with flexible sub assemblies will throw random errors that I have to correct by making it rigid and then flexible again.

2.I cant select edges or even objects sometimes also. I have to move the view and sometimes close the assembly and reopen it.

3. IT IS SLOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Much slower than 2018 and any other previous builds. I constantly get "Waiting for command to finish

4. Perspective doesn't show correctly (randomly)

5. Did I say it is slow, I mean really slow, to the point I have to get up and walk away.

6. Photoview 360 has slowed to the point that I can no longer manipulate the assembly with my preview open, It causes my computer to work so slowly that I get around 1 frame per second or maybe even less.

I am getting fed up with this "program", each year they raise the pricing and each year I get an inferior product to the previous year. I am seriously considering Autodesk because of my level of frustration at this point even though I have thousands of hours of work ahead of me to update to a new cad program.
