First of all, check what happens without your init file: `emacs -Q'.
If you see the same problem, try to note a recipe to reproduce it and
file a bug report, giving that recipe: `M-x report-emacs-bug'.

If you do not see the problem with `emacs -Q' then recursively bisect
your init file to find the culprit code.  You can use command
`comment-region' to comment out 1/2 of it, then 3/4, then 7/8, 15/16, etc.
You can use `C-u' with `comment-region' to uncomment the region.

This is a *binary search*, so it is very quick.  It is the way to proceed
always, but *especially* if your "Emacs system is complex".  Do not
try to debug a giant sac of stuff - break it down systematically.

If you have a question after finding the culprit code/setting, post it here.
