I have installed the FlyCapture Software and Drivers (v2.7.3.8). When I use the imaq toolbox functions everything works fine when my PointGrey Chameleon is plugged in. However, if I unplug the Chameleon and try to use any imaq functions (i.e. imaqtool), then MATLAB throws an error. See below. It looks like it is trying to do something with the Point Grey direct show drivers, even when the hardware is not plugged in and it chokes. Any thoughts on getting around this because I can't use the IMAQ toolbox at all without a PointGrey camera plugged in, unless I uninstall FlyCapture.

Always run imaqreset before disconnecting the camera. I have had similar crashing issues and I found doing the reset first gets rid of it.

Uninstalling FlyCapture 2.7.3.8 and reverting back to FlyCapture 2.6.3.4 seemed to avoid the crash. Not sure what I'm missing in 2.6 vs. 2.7 but this will probably suffice.
