Hello. !

Until a few days ago, I was using Poser Pro 11.2 on an iMac running on OS El Capitan with 32 Go of memory. Now I have a new iMac with Catalina 10.15.6, 8 GB of memory and a Wacom Intuos Pro Large PTH860 graphics tablet with the last driver (6.3.40-2) directly USB connected to the iMac.

I installed the trial version of Poser Pro 11.3.818 on it, … During my first few tries I discovered (horrified) that the issues I had with the iMac El Capitan are still present on the new iMac Catalina !

1. Poser’s camera orientation movements aren’t smooth, but with occasional sharp jerks, when the image is not suddenly upside down !
2. It often happens when I modify a character’s part of body, the movement I have just given goes partly in the other direction as if a spring held this part of the body.
3. Sometimes it also happens when I select a body part of a character, the "Library" window suddenly don’ t react to this new selection and gets stuck on the previous select. Then if I want to use the "Render" image function, the main window briefly displays the previous rendered image then turns uniformly gray and nothing more could happens.

Fortunately, I can still save my image, but I have to close the image file and quit Poser. Then I relaunch Poser, reload my image file so I can finally continue using Poser, until the next malfunction. This happens once or twice per hour of use.

Poser’s general preferences are configured with Tablet mode on.

What must I do so that my problems are eliminated ? Thank you for your answers
