- Other factors come into play, such as screen bleedings from one region
- to the other, that is, the screen writes of the other partition (that
- partition not currently being viewed) appearing on the active region's
- screen. This is caused by the background partition performing its screen
- writes directly to the screen instead of going through the system's
- BIOS routines, which are smart enough to route screen writes to the
- proper region's screen.
-
- Also, lock-ups may occur when computer instructions get "tangled"
- between partitions, and the computer is no longer able to reference the
- resources of the system. This usually results in having to re-boot and
- perhaps having to turn off the PC completely. For this reason, it is a
- good idea to test to insure that programs that update files that you need
- to maintain, run successfully in a multitasking environment prior to
- actually doing the update.
