Hi Claude,
I'm working with Lx Beams v5.6.0 (15424.1) OSX Mojave 10.14.6
I've found this odd thing: when I have objects grouped and I'm trying to drag them around, the object starts floating away from the cursor like a balloon.
When I ungroup the items it drags as expected. Regroup and dragging the group makes it float away again (the floating corresponds to the movement in any direction made by the mouse while holding down left click).
I can probably leave it ungrouped, it's not an urgent problem. Not sure if it's just me either...
Grouped items Floating
Is it possible to email a file with the group that is causing a problem? I'd guess that it is a specific type of object or set of circumstances that cause this to happen. If it can be reproduced, it can be fixed quickly. It wouldn't have to be the entire file, just copy and paste the problem group into a new file and send that.
