Now I'm here: see png. But how do I make the menu->view items clickable? After the first new tab (CTRL-N) they are clickable, updateMenubar() does not help.
In lyxfunc.C, LFUN_SIWTCH_BUFFER is not processed when there is no valid buffer. You can move line 422-438 to 355 to solve this problem. Then, the bigger problem is that lyx wll crash if you actually try to switch to a non-existence buffer in this window. (This is why my bookmark feature crashes). So, the real problem is to allow SWITCH_BUFFER to switch to a buffer that is opened in another window. Can you do it? Bo
