The last months Maple 2020 suffers from frozen interface behavior:
I simply wanted to save a file, but that resulted in a frozen window:
After 10 minutes the file explorer window appeared, but also this screen is unresponsive.
I reinstalled Maple last month, but that didn't help. Remarkably, the problem comes and goes. It seems to me that some java problem is making my life difficult.
ps I ran the process monitor of Sysinternals, but I have no idea if this has any relevance to the problems:
