I've had an issue with Instant Hijack since it was installed a month ago. I have installed the above mentioned bug fixes for Airfoil 3.4.1 and Instant Hijack. It seems that even the updated version of Instant Hijack will not peacefully coexist with Adobe Updater (Adobe CS4) on Snow Leopard. When Instant Hijack is installed I have a process that is writing 500k-1MB every couple of seconds to my disk. So much writing that my CPU and HD get hot and fans run at 3800 rpm.

Instant Hijack seems to be interacting with a process called VCstatus that is part of the CS4 Updater. It wasn't until I inspected the VCstatus process and saw Instant Hijack files in the opened files area that I realized the issue. I just uninstalled Instant Hijack and everything is back to normal now. It went against my better judgement to install Instant Hijack anyway...
