Recently updated to Microstation Connect 16, and the old issue of Tool Boxes drifting off the screen is apparent. No matter what I do (Shift+move back with the corner), they just revert straight back to off-screen. There doesn't appear to be a Popset setting in 16 neither. Driving me MAD!
The issue could be related to UPF corruption after the upgrade. Please try resetting UPF as described below
If issue persist, please let me know.
