I think I have broken something. When in a form, in design mode, the properties window, for either a form or a control, comes up at the top of the screen with no tabs at the top. Only the general tab data fields are available.

I have done two things recently but don’t know if they caused the problem or not.

I created some standalone writer documents and linked them to my database, and I installed MRI.

I have since removed and re-installed BASE to no effect. Help!

What is your operating system and LO version?

Sounds more like a corrupt LO user profile.

Or, alternatively, did you select any object of the form, before bringing up the Properties window ?
