We have an application that has recently added
ability to use the webcam(s)

We have been getting tons of reports about how the system freezes
when user goes to activate the camera usage.

Delphi 7, ImageEN 4.3.0

So far the only people to complain about this is
Win8 Tablets with 2 cameras.

No one has said anything about laptops with 1 camera or
in XP/Vista/Win7...

Will get some code snippets when I can.

Got some more info on this.

1) it happens after a fresh boot of the OS
2) when no other camera software is opened first

Apparently if they activate the camera software first, then our
program will run fine when it goes to do camera related actions.
If not, freezes every time.

Problem was there was a routine that was connecting/disconnecting
to the cameras really quickly. Removed this and made the it better
and so far no more locking up.
