We're using the 18.104.22.168 release, however, recently the docking module for the filter wheel fails to open. Clicking it seems to do nothing. We're able to change the filters reliably with the control panel or through the sequence. It's a Starlite XPress filter wheel.
EDIT: Seems to be an issue with changing the screen resolution, module might have been off screen with VNC. Resetting all modules made it appear again.
