Full screen problem after using CCD camera

My code
...
flb.new1("form1", B4PObject(1))
flb.fullscreen(true)
...
imgbg = ccd1.getimage(1024, 768, 3, "form1", "cam1")
...
form1.show ' try to make full screen again
form1.focus ' try to make full screen again
...

Problems is: after use ccd1.getimage, the original fullscreen form1 can not show full screen. The top bar shows the Start and Time.

How can I resume to full screen?

Did you try to call flb.fullscreen(true) again right after the call to getimage?

Yes. That works. Thanks.
