Hi there. When I use RStudio 1.3.878, it occasionally crashes or gets stuck when I conduct copy and paste operation. When it happens, I have to force quit the RStudio.
Actually, the previous release of RStudio 1.3 also has this problem, which made me back to the RStudio 1.2.5033.
My environment is as follows:
