No problem here (Win 10 1709, 64 bit, Laz trunk/fpc 3.0.4 32bit). I replaced each TCurrencyEdit by TFloatSpinEdit, though, because I did not want to install rxnew. In the attachment you can find my modified version of your demo. If it starts for you correctly, too, then the TCurrencyEdit or some other code in rxnew might be the culprit
