MegaWizard Plug-In Manager hangs when making a PLL (Quartus II v14.1.1)

[Altera_Forum]

The following problem is completely repeatable: 

 Within Quartus, in IP Catalog window (default position on right of screen)select: Installed IP -> Library -> Basic Functions -> Clocks; PLLs and Resets -> PLL -> ALTPLL dialog: Save IP Variation file name: /home/rac/FPGA/my_first_fpga/pll.v file type: Verilog  window: MegaWizard Plug-In Manager [page 1 of 12]select speed grade: 6 try to change the input clock frequency  WINDOW IS NOW UNRESPONSIVE   Nothing in the MegaWizard window is active, and if I cover/uncover it with another window, it won't update.   I can eventually close the MegaWizard window using the close box in the upper right window frame.I then get the dialog: Metacity MegaWizard Plug-In Mnager [page 1 of 12] is not responding. choose Force Quit or Wait   With a Force Quit, I am back in the Quartus main window and I can exit normally.  My system and install:  OS: Centos 6.6 (64-bit) fresh installwith all the Altera listed libraries installed except libzmq3.i686 (it wasn't in the repo)  Quartus II version 14.1.1 (update 1)installed from downloaded files Quartus-web-14.1.0.186-linux.tar QuartusSetup-14.1.1.190-linux.run   Another note: I get the exact same behavior with this Quartus on Linux Mint 17, and on two different computers. I installed Quartus on CentOS to see if there was some "magic" associated with the "approved" distribution.  Thank you

7 years later, this issue still persists on Quartus 21.1 and Ubuntu 21.10. Solved by resizing the window before doing anything.
