Access Violation after closing

After closing VVVV (via DoQuit(VVVV)) this pops up:

Exeption EAccessViolation in module vvvv.exe at 00007B42.
Access violation at address 00407B42 in module “vvvv.exe”.
Read of address EA324E31.

using beta27 on win7.
renderer fullscreen on second monitor.

hei armin, if this behaves the same in b27.2 please provide a little patch that shows this. else simply use b27.2

b27.2 is the solution
