GUI problem in CubaseSX (Mac)

Hi, i’ve been testing your vibeEQ and i think it’s brilliant and want to buy but i have a GUI problem. When i open the plug, make my settings, then close it, then open it again the GUI had disappeared with just a blank white screen, can you help?

cheers.

Mac Quad G5
Mac OS 10.4.11
Cubase SX3
RAM - 4.5Gb
Metric Halo 2882 interface.

which version of quick time do you have installed?

I pulled this from a thread - mac area at cubase.net:
cubase.net/phpbb2/viewtopic.php?t=69253

a long shot, but worth a try.

greetings
