Hi Serge,
Ok thanks.
We think your IE11 bug is one that we have corrected already on Datafari EE, but we have not pushed it yet on Datafari CE. Unfortunately you'll have to a bit patient then, as we are a bit of schedule on that one: Datafari 5 (yes, 5!) will be out probably around end of August, and it will contain the fix.
There is no easy workaround to implement in the meantime, sorry for that.
On a side note with regards to your FF testing and your mention that links do not open. Is it only links with the accents ?
Regards,
Cedric
