Half a minute delays on every change influencing total project duration

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
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.
