PostPage. Both times, and this was using 2.5.26, 2.5.27, 2.5.28, and 2.5.31 (CVS). > Could it be that some X-server properties could interfere with the > calculations > and that they cause this different behavior? No, because the panframes are created around the edge of the screen, which FVWM reads from X11. You'd really notice a difference if that weren't the case, since you'd be paging in the middle of the screen. > Does fvwm read some other properties beside .fvwm/config? Yes, but nothing which would interfere or cause problems with the example config you supplied. > What could be of use? X-socket dumps and analysis? Compile fvwm with debug > options? Try to use 2.5.28 on old xserver or 2.5.26 on new server? Try a different X server, but this is not likely to be much problem. What you could do, if you're really sure that the problem exists between FVWM 2.5.26 and 2.5.28 (and thereafter) is to to use git-bisect to find the commit which introduced this problem. This assumes you know git. See: http://github.com/ThomasAdam/fvwm -- Thomas Adam -- "Deep in my heart I wish I was wrong.
