Hi,
I made a fast check here and I couldn't reproduce it, but is this an xls or xlsx file? There are 2 things to be aware of:
1) Currently we support cfs only in xls, not xlsx files. We are working in cf support for xlsx (it is along with charts one of the 2 important things still missing in xlsx support) but a lot of workload has kept it delayed.
2) We also support only xls2003 style cfs, not 2007 (which are completely new). Again, this should be fixed by 5.7 when we reimplement cf support.
Can you email me a file that shows the issue to adrian@tmssoftware.com so I can take a look?
Thanks,
Adrian.
