I have started to experience that i get the spinning beach-ball when running SecureCRT. First i thought this was because i was using the "log session" and the output was so fast that the program were struggling to keep up.
My Info:
Terminal: SecureCRT + FX

v8.5.3 Mac)
Computer: MBP(Retina, 15-inch, Mid 2015, OSX Mojave 10.14.3)
Today i experienced it again when logging into a remote linux machine with SSH and i ran the "mtr 8.8.8.8" command. While doing this you get the option to press "d" to change the display mode and after i do that the terminal window becomes "sluggish".
mtr example:
1. I press "d"
2. The cursor disappear on the window and the mode changes.
3. I press "d" again and the spinning ball appears.
4. Now i am helpless

and all i can do is wait, but nothing happens.
Log session:
1. Login to network firewall
2. Enable log session (save somewhere)
3. run the debug command (once it starts to spit out a lot i get the beachball), i don't have this problem when using my the terminal on my mac for instance.
Would reinstalling SecureCRT help, what could be the issue?
I have stock SecureCRT with a .ini file to get cisco syntax highlighting and that is pretty much it.
