I’ve noticed some odd behavior when trying to deselect a group when multiple elements are selected. Instead of deselecting the group, it instead selects one of the items in the group. Here’s how to reproduce:
1) Put a bunch of elements in a plot, and group two of them together.
2) Select everything on your page via Control-A (or however you want).
3) Using Control-click, deselect a normal element. Works great – only that element is removed from the selection.
4) Now try to deselect a group with Control-click. If you Control-click on one of the elements in the group, it will *select* the item in the group instead of deselecting the entire group.
This is a pain, because if you want to select everything on a page except one element that happens to be a group, life gets a lot harder. It looks like it works properly if you Control-click on a part of the group that doesn’t contain any elements, if there happens to be such space in your group.
