Webwindows do not update

Targets Web

I have a shell program who carry on some operation, I have written it in xojo.
When I call it with operation who take short time, i.e. 10 sec, the result appear correctly into the windows.
But if the processing time is longer, i.e. 90 sec, the windws will be not update and show the result from the shell program.
The shell program return the correct string to be showed, I have checked with a degug session.
Any idea on how update the browser widows upon the end of the shell command?

Thanks

Maybe you can provide a sample project (you can zip it and upload it to the forum).
Someone may take a look and give you ideas.
