non-Modal FBPopup disappears

Hi,

I have a simple popup that I am trying to show from the FBCreate() function of
my FBTool:

	FBPopup test;
	test.Modal			= false;
	test.Region.X		= 300;
	test.Region.Y		= 300;
	test.Region.Width	= 250;
	test.Region.Height	= 100;
	test.Caption		= "Test Popup";
	test.Show(this);

The problem is that when I open the tool, the popup shows for one frame, and
then disappears. If I derive a version of FBPopup and put a breakpoint in
Close() I find even that's not being called.

However, if I set Modal to true, then it works fine, but then I can't interact
with my base tool. What am I doing wrong? Are non-modal popups not supported?

If so, is there another way I can launch interface windows from my tool? Maybe
launch another tool I create?
