Behold makes it very clear up front that at the present time it doesn't export GEDCOM.
I believe you should have done a bit of research on Behold, particularly in regard to the cost. You buy it once and then *all* future updates and upgrades are free.
If you are familiar with Tamura Jones and his software reviews you know how hard he can be. His review of Behold, even after mentioning the lack of GEDCOM exports, etc. ends with high praise for the product - something Tamura isn't particularly noted for.
You might also note that Behold is only one of 4 genealogy programs that has qualified to display the Windows Logo on their package- something neither FTM, Legacy, RootsMagic 5 has done.
Lastly, I've no connection with Behold other than a *very* satisfied user who is looking forward to the next update.
