I can't reproduce with the slightly later version 9d1ae05442 on GNU/Linux with a pgtk build. When scroll up and down (only so far as to keep point at the closing paren of the defun), I'll see the child frame displaying the "(defun ...)" line whenever I stop scrolling for a second. After doing that for I while, I checked that `(frame-list)` still contains just a single frame. How is that for you? Do you have many frames in there? And do you recover from the freeze? Does doing the recipe with debug-on-quit set and then doing C-g when the freeze occurs shed some light? Bye, Tassilo
