PB 12.6 resize event before open event

Someone of you has problem with PB12.6 (build 4081) resize event

In my case the resize is called before the open event and just if I call my windows using OpenWithParm instead OpenSheetwithparm

Using PB 11.1 the order is Open the resize even using OpenSheetwithparm

Any hints please?

Thanks a lot

Regards
