Why does Qsys / Platform Designer close when trying to open, save or save as? Is it just me?

Hi Anand,

I tried creating a new project and opening Qsys, then created a simple design so there were no errors then attempted to save the design and, as before, the window simply disappears. This also happens on the laptop, which still has version 17.0 installed. Note that I checked task manager after the window had disappeared and could see no evidence of a process associated with Qsys still running, which suggests it has stopped completely..

As it happens I have recently did a clean re-install of windows 10 on another laptop so I installed Quartus Prime 18.1 on that and it did not have the same problem. I can't think what it might be but there's something in common between the two systems that show the problem that is different on the one which works so i'll need to see if I can work out what it is. I'll post any findings if I fix it.

Regards

Neal
