UR 4.2a - Windows 10 - Data Explorer locked

[Roaster]

Hi,

still using UR 4.2a (Yes!) and upgraded my Win7 to Win10 previously. I now noticed that when opening an existing UR database that the Data Explorer (tree) is locked and cannot be scrolled or edited in any way.

The content is available just editing is impossible.

This also applies when creating a completely new database.

Is this a known issue with UR 4 and Win10? Can this be solved somehow?

Thanks,
Michael
