The initial Beta 4 version had an unfortunate issue with grid editing. The text cursor did not behave correctly, which made it impossible to edit the grid contents.
If you were one of the first to download Beta 4, you may run into this issue.
We have uploaded a quick fix that resolves this. The package name and version are the same as before. You will need to uninstall the initial Beta 4 version before you can install the fixed version. All preferences will be preserved after reinstalling.
