Thank you very much for the report and I am very sorry to hear about the issue!
To understand the issue better, I would like to ask a few questions:
- Which OS and Archicad version does the issue happen with?
- Does it happen only in Layouts or with Floorplan/Section/Elevation view, etc...
- Does the mouse input work with other actions like Mirror, Rotate, Elevate, or when editing/stretching other 3D elements? Or does the issue only happen when dragging a textbox in layout?
Looking forward to hearing from you!
