My guess is that conflict resolution button made toolbar a bit wider that when there's no conflict resolution button available.
Solution for this is to resolve all email conflicts or make your logo smaller (less wide), so there's enough place for toolbar to be fully displayed.
activeCollab grew a bit in the past couple of years and number of modules that add buttons to toolbar also grew. New version of activeCollab interface will have a smarter solution for increasing number of toolbar items, but in activeCollab 2.x, the only solution is to have a logo that's not too wide (something like original aC logo).
Sorry, there's currently no way to automatically resolve email conflicts, unless you configure incoming mail so it does not create conflicts (allow everyone to submit comments via email for example).
We'll work in this area for the upcoming activeCollab 3, so it will offer more options in the future.
I've attached screenshots of two different screens to demonstrate the issue.
Is there a restart/reboot button in aC
I'm thinking if we can restart, we can make this disappear.
I appreciate your thoughts.
