Q. The terminal is locked on a screen, for example I pressed the

or access to a Table# the terminal will not allow me out of the screen and I
want to avoid power off.

1. Connect Keyboard
2. ALT CTRL DEL to bring up Task Manager, select X300 FrontEnd Thread
Window and select End Task

1.25 Terminals “freezing” when very busy. (1.6.0.9/1.6.0.10 ONLY)
Q.
 The terminals seemed to freeze or lock out, this only occurred when the
site was very busy.
A. This was due to the settings within mfull.ini. The EJ, Tlog and Ctrans were
all increased to cope with the throughput. Also the customer was not using
Close transaction, therefore “Method of retention on Closed Transaction”
should be set to Not Retained.
1.26 The X300 will only allow so many items then displays
insufficient memory
Q. The message “Insufficient memory too many items”  appears after
entering lots of items on one transaction or on one table.
A. This was due to the settings within mfull.ini, the MaxRegBuffer was set too
low, to change the registration buffer to allow more items per transaction
please edit the mfull.ini file as detailed:
1.  Perform SHUTDOWN on X300, 2. Tap screen 20 times, 3. Open wordpad
and edit \Hard Disk2\X300\Windows\Mfull.ini
