How can I tell whether I have F-Cam Drivers installed or not, and if their version is OK? I installed BlessN900, it didn't prompt for any additional drivers (neither can I find them under Installed and Not Installed in FapMan), and after a reboot, it just works.

Should the standard cam app work as before? I've noticed that after taking a photo with it, it displays a black screen with "Processing Image" first (it didn't use to do this).
