What can it be happening?

Hi Malcon.

While instaling version 1.7.3 did you allow the installer to go through the database install? This will make sure all your SF tables are updated with the current structure.

After that, once you rebuild the your StrataFrame Inherited UI with DevExpress 9.1, I would make sure the GAC has the latest DLLs. You could even delete them all from the GAC and copy back from the Common folder (C:\Program Files (x86)\Common Files\MicroFour\StrataFrame). This will make sure all DLLs are current. Still, make sure you don't have old DLLs around the place, since Visual Studio could be pointing to some of them.

Let us know how it goes...
