Bobo,
Potential UI issue in 3dsMax2009sp1 x64.
Whilst renderer is selected as Krakatoa, trying to click to open any of the Krakatoa Rollout UI’s from within the VFB causes a script crash.
–Unknown property: “open” in undefined
Script that fails is:
Krakatoa_VFB_Methods.ms
–line 207.
Regards,
Mike
Update on this bug…
The error only occurs if you select Krakatoa as the renderer and then open up the VFB and click on one of the open rollout buttons.
If you open up the krakatoa GUI first, all is well 
Mike
Thanks, will look into it.
The funny thing is I do not have a license of Max 2009 neither on my machine nor at home.
But I think I found where the error is and might have fixed it, but cannot test it.
Attached is an updated version of the MS file responsible for the VFB functions.
Could you please replace the existing one with this (after creating a backup, of course) and test to see if it solves the problem?
The file is located under the Krakatoa installation folder inside the \Scripts folder.

Sorry. Tried the new code but still crashing.
Listener window dumps the following information:
– Error occurred in navigateToKrakatoaRollout(); filename: C:\Program Files (x86)\Frantic Films\Krakatoa\Scripts\Krakatoa_VFB_Methods.ms; position: 7607
– Frame:
– theRollout: Rollout:Krakatoa_GUI_Main
– called in mnu_OpenRollout.picked(); filename: C:\Program Files (x86)\Frantic Films\Krakatoa\Scripts\Krakatoa_VFB_Methods.ms; position: 8106
– Frame:
MAXScript RCMenu function Exception: – Unknown property: “open” in undefined <<
The editor opens the Krakatoa_VFB_Methods.ms file and flags up line 213 as being the problem…
I think ALL the RCMenu items are failing in the same way…
Feel free to send an update and I will test again 
Mike
EDIT:
I looked again at the code and made some changes.
Please try it out and see how it goes. At least it should not crash. It might actually work ok this time…

All sorted now.
I have tested as many different combinations I can and haven’t been able to break it once…so all looking good now!
Thanks,
Mike
Good to hear!
We are planning a 1.1.2 minor update soon which will include this fix and a couple of other fixes and small additions we made recently. Among them will be revisited and significantly updated [H] buttons in the Save Particles rollout including caching for instant access, pattern filtering for values and paths, “latest on top” order option and an option to hide the full path; support for V-Ray Physical camera distortion to match V-Ray renders in Krakatoa, and some bug fixes.
At the same time, we are working on 1.2.0 with major new features.
