SFScreenLock V1.1x is now effective on OS5 devices!

SFScreenLock is a simple SFX plugin extension that enables you to "freeze" the screen display, enabling you to perform tasks without updating the screen or causing flicker, then "unfreeze" the screen when your tasks are complete.

NOTE: The screen locking function in SFScreenLock requires PalmOS 3.5 or higher. If you attempt to call the ScreenLock method on a device running on version of the PalmOS lower than 3.5, it is simply ignored. However, it also does not work (and is silently ignored) on the Visor Prism and Treo models. The modifications that Handspring has done in order to enable 16 bit colour make the screen locking function unusable. It does work on other 16 bit colour devices such as the Palm M505 and Sony Clie T615C.
