We have some Apps that are slow to reload in 12.0 vs 11.2 but I haven't seen a hang on open. We were doing both Desktop and Server.
We want to move to 12.1 so I hope someone has input. When QlikView hangs, what does your TaskManager show?
Is there a 1 core spin?
Is it flat ie no activity?
or Is there multi-threading?
If you look at the process is the RAM moving or CPU usage moving?
All the best, Adam
