Problem with laser and an MC55

Hello.

I have TelnetCE with WEB profile, version 7.3.175

I have 2 WEB sessions.

If I use a single session, everything works.

But if I use 2 sessions connected at the same time, sometimes the laser stops to work, randomly.

There's no a particular part of the program I'm in use, the laser works for the most time, but sometimes it stops, with no messages or errors.

Switching to the other session re-enable the laser, and this problem occurs on both the sessions (that runs different programs).

Finally, the problem occurs from 10 to 50 minutes I start to work.

I used a previuos version of TelnetCE (7.3.69), but problem is the same.

Some other info: The OS is Windows Embedded Mobile 6.5, I'm already using the "WEB Alternate Browser Support" for both the sessions

Thanks
