Staring today I just can't move the tabs around in CCS or resize for example the Project Explorer tab. If I try to move a tab, the text in a tab will be underlined but I just can't drag it anywhere. I have created a new workspace but it didn't help. I have also STM32CubeIDE installed, which is also based on eclipse and it is still working fine.
CCS version 10.3.0.00007
macOS Big Sur 11.2.3
