Hi,
After install of beta 6 I'm facing problem whilo opening package body/procedure with ctrl + right click from sql/program window. The package opens, but pl/sql developer gives me error and it's not focused on dedicated procedure:
Access violation at address 0000000002F45F19 in module 'plsqldev.exe'. Read of address 0000000000000048.

When i return to beta 5, this works without any error. With beta 6 i'm getting this error both when upgrading, or clean install.

And please consider option to disable AutoReplace while typing comment section.

Thanks.

I have reported the same problem, and according to Marco Kalter the access violation issue has been solved in beta 7
