I try the same under Windows , there is no problem. The problem exists only under Linux / GTK

Problem seems particular to sparta editor. I cannot reproduce it in the regular form designer.

Note that the multi-select key under regular editor is shift, not ctrl.

It was my fault, I did not clarify very well.
I mean the rectangle component select, which activates by hold the "Ctrl" key.
I Confirm, that the issue comes only under "Sparta" editor.

So you have Sparta docked forms editor installed I guess. Not only Sparta MDI.

Can you please test with package DockedFormEditor, not Sparta_DockedFormEditor, if problem still persist?!
