Version 1.12 -- 2002-02-07

This update fixes some minor bugs. Here's the list of changes:

Fix: Rename windowClose/frameClose to evWindowClose and evFrameClose to conform to the documentation.
Fix: Implement a work-around for a nasty bug in some versions of Windows 98 that caused a floating point error and program abort on some computers (CreateWindow changes the floating point precision to 53 bit). (ap)

Availability of Borland compilers -- 2001-10-01
