I am currently using Aquamacs 3.4, Emacs 22.214.171.124, and Org mode 9.2.5 and I typically have my frame split vertically into 2 windows. Each window carries 2+ different buffers whose names are in the tabs above. Here's an example:
When I switch to agenda-view with C-c a, the tab bar and buffers over my right window (where the agenda shows) disappear as shown here:
When I exit the agenda with q, the right tab bar does not return and, instead of the original 2+ buffers in that window, I am left with only 1.
At this point, if I kill the buffer on the right, the other (now hidden) buffer in the right window is revealed. Furthermore, I can M-x tabbar-mode once (getting rid of all tabbars) and then M-x tabbar-mode again to reveal all tabbars correctly again.
Ultimately, my problem seems to be that agenda-view is turning off tabbar-mode specifically in the window it opens. As it stands now, my fix is to turn off all tabbars and then turn them back on again, but it's a little bit of a pain.
Has anyone experienced this behavior and know of a way to disable it? Thanks for any info!
