We're looking into this.

Luckily we have one unit that has this problem so it's being sent to David so he can take a look at the issue and come up with a solution. He usually does :)

Some further info on this problem. It still exists in version 3.12. I attempted to do a re-flash using the USB disk and it still hangs. It also hangs if you try to do it from the System menu.

Also, somewhat more serious is that it now appears to be unstable when ejecting the disk in that the DM42 is frozen and does not respond to any key press. It is stuck on the "USB write mode ..." screen with "Press EXIT key to end" but only the reset button can unfreeze it. When you do it displays this message -

Oops, RESET in protected area.
Please report the following info if the system has hung:

Reg Id d3770002, fw 3.12

Press EXIT to RESET the calculator...

OK, that's a new development and it might help point David in the right direction. Thanks for that, I'll pass it on.
