ScreenChooser is Shareware 

ScreenChooser is not free. You are given the opportunity to try out ScreenChooser for a entire month, after which you are obliged to either pay a small registration fee, or delete your copy of ScreenChooser. For complete information on how you can register your copy of ScreenChooser, we ask you to read the registration document found in the control panel’s online help. You can reach the registration information by clicking the “Register” button in the control panel, as described below. 

Reaching the ScreenChooser Online Help

Changes and Bug Fixes since Version 2.2 

As version 3.0, a complete rewrite of version 2.2, resolves many incompatibilities that plagued the previous version. What follows is a list of the major bugs that have been corrected: 

    1. On Performas, ScreenChooser will no longer screw up desktop patterns. 
    2. ScreenChooser now runs under System 6.0.8 . 
    3. Better error checking prevents crashes and reports out of memory errors before they cause trouble. 

In addition, ScreenChooser V3.0 adds many new features, which consist of the following: 

    1. Improved control panel design. 
    2. Option to display images randomly or sequentially. 
    3. Ability to limit the number of colors in backdrops, thereby saving memory. 
    4. Option to have backdrops changed while you work. 
    5. External image loaders for easy upgrades. 
    6. Helper applications allow you to change backdrops on the fly. 
    7. More image display options, such as maintaining an image’s proportions. 
    8. Hyper-text online help, for easier access. 
    9. Improved error reporting and more helpful error messages. 
    10. On backdrops smaller than the screen, the desktop pattern fills empty spaces, instead of gray. ScreenChooser can now be used with other desktop pattern enhancers. 

Known Limitations and Incompatibilities 

ScreenChooser V3.0 corrects many problems and incompatibilities that plagued the previous version. In the interest of having this version replace ScreenChooser V2.2 as soon as possible, some limitations with version 3.0 were not resolved. These limitations, however, are minor and should not affect the majority of users. They are as follows: 

    1. ScreenChooser V3.0 will not run without color QuickDraw. Essentially, this means Macintosh with the 68000 processor, such as the Macintosh Plus, SE and Classic, as well as a few PowerBooks. Attempt to run it on such machines may result in a crash at startup. 

Corrections to these limitations, as well as the release of a PowerPC native version, is planned for future updates, perhaps as version 3.1.
