Mac OS Mojave Issues with Painter 19

Hey Guys

After waiting a period of time and paying attention to the topic here, I've just recently upgraded to Mojave. Unfortunately I've noticed an issue with Painter 19. Whenever I open or save a document the program freezes for @ 10-15 seconds. 

Another problem that noticed with High Sierra (that hasn't disappeared) is the curser not working for about the same amount of time after having been working in other applications. I talked to Corel tech support about this issue a few months ago, but got no follow-up.

While neither of these are deal breakers, they are pretty irritating and I'm looking into downgrading OS (but not looking forward to it).

I'm on a 2013 3.5 GHz,Intel i7 iMac with 32 GB of memory and a NVIDIA GeForce GTX graphics card.
