I thought this was fixed, but recently it seems to be back. I use a separate, special-display frame for *Backtrace* (and for other buffers whose names are of the form `*...*'). Frame *Backtrace* gets created OK (but once it did not - a weird error was raised - see bug #13113). But as soon as I click any part of it with the mouse (e.g. mouse-1), that frame disappears completely. I cannot use the debugger at all. Here was what I said in bug #8789, for info: Sometimes I can grab the border of the *Backtrace* frame, as usual, and resize it (even though it goes back to the default size when I hit `d', as describedearlier). But sometimes I cannot: as soon as I touch the mouse to the frame edge and try to drag it, the frame disappears! I can just touch it (e.g. click it) without it disappearing, but as soon as I try to drag the touched edge, the frame disappears. It does not matter which edge (e.g. bottom or right) I try to drag. No idea what is going on here - I have never seen anything like this. This happpens systematically when I enter the debugger in a certain context, and it never seems to happen otherwise. But that context is far too complex to try to communicate. Suffice it to say that this happens. When it happens I see nothing additional in *Messages*, and there is no crash. The *Backtrace* frame just disappears, and the mode line indicates that I am no longer in a recursive edit - IOW, the debugger is exited. And if I explicitly visit buffer *Backtrace*, I see that it is indeed empty. It is as if trying to drag the frame edge is (sometimes) the equivalent of hitting `q' in the debugger. But now it is not only trying to drag the frame border that causes this. Any mouse click on the frame, anywhere, causes it. I mention that older bug here because Martin apparently recognized the frame-disappearance problem (& cause?). He immediately replied: "This should have changed now." And indeed, it did seem to be fixed. IOW, presumably he or someone else made some change that helped. I'm hoping that the same or similar fix can be made now, or at least that that previous bug report will help someone fix this current problem.
