when i switch to preview mode, sometime i can not be back to design mode. anyone else meets such bug?
no, have you turned off all Chrome extensions?
i am working on Yosemite beta, is that a reason?
Aha! nice. Then I suppose you are running latest Chrome version with no extensions?
i have not any chrome extensions be installed.
Hey @zfe try to hover your mouse over the left most part of your preview screen and see if the sidebar appears. There you should be able to unclick the preview icon.
it is solved.
i used to create an interaction to one class, later i delete the interaction, and then the bug happened.
i just reset the class "name" to none, the bug is gone.
i don't know why, but let it go.
