I am getting the following error when running ppwatch config.

Exception EAccessViolation in module ppwcfg.exe at 002ED150.
Access violation at address 0447E150 in module 'ppwcfg.exe'. Read of address 00000014.

The error is reproducible. I have a watch with two processes. If I change one of the output events in Process2 then click on Process1 the error message appears.
I have experimented and found that it is linked to the fact that I am viewing Process2 at normal scale, and Process1 with Zoom Out. If I remove the Zoom Out, the error does not happen.
I have Watch
I can give you an example config and detailed instructions to reproduce if required.
