Half a minute delays on every change influencing total project duration

Hello,
this is a problem that I’ve been always experiencing in Storyboard Pro 20: I add a scene/panel or change panel’s duration and before I can continue working I have to wait for a good half a minute for the program to unfreeze (cursor showing the program working…).

Is this just my computer’s issue or is there a way to change some settings that could eliminate this problem? Is someone else experiencing this?

My setup:
Storyboard Pro v 20.10.1 (16823)
Windows 7 Professional, SP1
i7-7700 CPU @ 3.60GHz, 3,60GHz
RAM 32 GB
10 GB free disc space
NVIDIA GeForce GTX 1060 3GB

Update Storyboard Pro 20 to the latest release 20.0.2, build 20.10.2 (17538). Also upgrade to Windows 10 (64-Bit), it is the supported version.
