Question CT 7.0 Cocoa on OSX Catalina strage behaviours

Hi CT Dev Team & Users,
I observed a strange behavior using CT 7.0 Cocoa on OSX Catalina regarding two functions :

1- the TListBox sorted function doesn't work ; I tried to set it as True in IDE or during execution, the items are not sorted. I also tried setting false then true, didn't work.
Any idea ?

2- when I click on a component on a form, I have to click several time to perform a task ; as if the focus wasn't there... e.g. a button with a onclick property set to some code, when executing the code, I have to click 2 or 3 times to execute the onclick method.
Any suggestion ?

Thanks a lot for your advices.
