It sounds like you are instantiating PLLs inside of QSYS. I don’t have too much experience with that as I typically instantiate them at the top level with the standalone qmegawiz command line application. It is started from the ip catalog in recent versions of the quartus GUI.
One definitely needs to be diligent to expand the window first before touching any other part of the PLL GUI, to avoid the 100% of the CPU core lock-up.

Jeff,
Yes, the ALTLL megawizard is Qsys function.
It is hard to re-size a screen that is displayed for less than a second.
Thanks for helping -
