Again, as long as you are the only one with the back trace, there is 
nothing I can do to help you. Are you sure you don't have any local 
changes to FlexiSheet on that machine?

The line 407, where your back trace reports the problem looks like this:
                    if ((x >= visible.origin.x) && (x <= maxX)) {

visible has been accessed already. What you could try to do is to clear 
the memory used by _colWidths and _rowHeights in [FSMatrix 
-initWithFrame:] by calling memset() and also in the various places 
where they get reallocated. If these variables get used without proper 
initialisation then the program may go astray as in your back trace.

But this definitely is an application bug. We may as well look into this 
after the release.
