Clarion Browse window appears behind Form window

I am writing a clarion mdi application.
I have one mdichild opening as the default/splashcreen. On this mdichild I have several browses on different tabs.
The problem is that when I open a form connected to a browse it shows up behind the default mdichild. I have tried to set the forms to modal but it doesnt help. Instead I get a thread error.

Any suggestions?

Browse procedure must be STARTed, and both Browse and Form must have MDI attribute.

This is not just a browse and a form, but a window containing several browses, with corresponding forms.
All the forms show up behind the window. All windows and forms are mdichilds.

In other windows where I have browses and forms they behave normally. It is just this window that will not act ‘naturally’.

well, find the differences.
