When using the 70g beta release on Windows XP, I can do the following:
1. Run gvim -u NONE 2. Issue :tabnew 3. Open the command line window with 'q:' 4. Switch tabs with 'gt' Now neither the vim window on the tab I just switched to, nor the command line window on the previous tab are in a usable state. It's a bit hard to describe what's going on, but it looks a bit like the editing window that 'gt' takes me to is being treated as a command line window. There are ':' characters drawn down the leftmost screen column, and hitting <CR> causes vim to display "E199: Active window or buffer deleted". I notice that if I use the mouse to click on an inactive tab, vim will not switch tabs if the command line window is open. Should 'gt' also refuse to switch tabs in this situation?
