I use the non-bootstrap menus for the left navigation on my site. Since the Tiki 14 beta began, this has been an issue. Every page that has content to load in the left navigation column will show all of the menus associated with the page upon loading the page, and then they stop showing. They only show for a second or two.
I have not been able to find a solution to this problem. I've read that it has occurred in past Tiki versions, and I am curious if anyone else has encountered this issue.
