Incompatibilities & Limitations

DHTML Menu Builder is optimized to take advantage of the great features in Microsoft's Internet Explorer 5.5 and above.

Because of Netscape Navigator 4's lack of support for standardized features, some features in DHTML Menu Builder can't be reproduced on other browsers.

Known Style Issues
Below you will find a list of style settings supported by DHTML Menu Builder that will not work on some browsers:

• Drop shadow and transparency effects
  These effects use some proprietary features of Internet Explorer 5.5 and 6.0, so no other browser will be able to render them.
• Raised and sunken borders effects on the commands selections
  These features are not available under Netscape Navigator 4
  The resulting menus will not show the effect
• Colored borders
  These features are not available under Netscape Navigator 4
  The resulting menus will not show the effect
• Cursors
  The support for different cursors is not available under Navigator 4
• Border Colors
  Netscape Navigator 4 does not support different color borders in the same group.
  The resulting menus will show a single colored border taken from the setting for the left corner.
• Context Menu
  With the exception of Internet Explorer 4 and Opera, this feature is only supported on browsers running under Windows.
• Fonts
  Under Netscape Navigator 4, fonts may appear slightly smaller, especially when using the Macintosh or Linux versions.

Netscape Navigator 4 specific issues
Netscape Navigator 4 is a very old browser with a huge list of problems. Here you will find some of the most common issues that directly affect the menus created by DHTML Menu Builder.

• Resizing the browser window crashes Navigator or makes the menus inoperable
  This is probably the most annoying bug in Navigator 4.
  
• Font sizes under Netscape Navigator appear smaller
  Because of a bug in Netscape Navigator 4 that forces us not to use in-line style sheet declarations, DHTML Menu Builder converts font sizes from pixels to points. Under some font types and sizes, this may cause the fonts under Navigator to appear slightly smaller than in other browsers. The cause of this problem is outside the scope of this document, but if you would like more information try these links:
  • PHP Builder (Mail Archive)
  • DejaNews Search Query (+ttyle)
• Browser crashes when loading a page with the menus
  Under some circumstances, very old versions of Netscape Navigator 4 (specifically 4.05 and 4.08) will crash when loading the menus.
  This is usually caused by the combination of the menus' scripts plus some other non-Navigator compatible code in your page, including scripts generated by other programs.
  You should try previewing the menus directly in Navigator. Alternatively, you might try creating a page that contains ONLY the menus and the toolbar. If the browser does not crash with the menus alone, then your pages contain some code that, when used in conjunction with the DHTML Menu Builder menus, crashes the browser.

Opera 5 and 6 specific issues
This excellent browser has made its way from a purely simple browser to an almost perfect browser in terms of compatibility with the W3C standards.

• Commands do get selected when hovering over them
  Opera 5 still has no support for several DOM properties that are required for menus highlighting. As a result only the images change when you move your mouse over menu items.
• Resizing the browser window crashes Opera or makes the menus inoperable
  Just as Navigator 4, Opera 5 may crash or improperly render the menus after resizing the browser window.
