If I go to ban someone from a group I manage, Alchemy simply closes down on me once I select their name to add. I have to actually log in on a different viewer to be able to do this. I am on a Mac and I had this same problem during Beta too. :/

Uncertain if related or not, found steps to reliably crash the viewer when using the group ban window on a Win10 system.
Step 1: Open the group ban window
Step 2: Use the resident chooser to select someone, anyone
Step 3: Do NOT click ban resident yet. See that name you got in the ban resident window now...
Step 4: Click that name!
You should be crashed.
The window is very similar to the group invite dialog, except the group invite dialog doesn't crash when you click a name. In fact clicking a name does nothing, and I expect it to do nothing. I clicked the name in group ban purely by accident.
This does this on Dire 4.0.7 (39131) and current Live alchemy.
That is what happens exactly! I hope someone can find a solution to this as it is a pain having to swap to another viewer just to ban a name from a group. :/
Crash fixed in next release.
