I tried this on my computer running Win95 3.0.950B with Netscape
4.04 Swedish version. Strings that goes over 1079 chars tend to
crash netscape...

Norton Crashguard reported the following:

NETSCAPE.EXE caused fault #c0000005 in NETSCAPE.EXE at address 014f:00532b9b
MSG("Netscape", WM_CREATE, 00000000, 0088E6F4)
