The following is the minimum Web browser supported, by platform, as tested with the R5.0.5 Domino Java applets.
NOTE: Internet Explorer is not available on AIX 4.31, and is not supported on Macintosh PowerPC and HP-UX.

2 Using Netscape 4.6 is not recommended because of a known LiveConnect issue. Specifically, use of the Outline, ActionBar, or Editor applets may generate a security exception and eventually cause the browser to hang. Upgrading to Netscape 4.61 solves this issue. Also note that Netscape 4.51 does not exhibit this problem. Some Notes Templates and other features that require Java may be affected by this limitation.
3 When using Netscape Navigator 4.61 for OS/2 you must also install the IBM JDK 1.1.8 for the Domino Java applets to work properly. If the IBM JDK 1.1.8 is not installed then the Domino Java applets will revert back to corresponding HTML elements.
