What version of netscape I have aol6 IE5.5 and netscape4.6 and have had very few problems
Freezes and crashes occur frequently when memory resources low With your system running check system resources that is done by Start, settings, control panel and click on the "system" icon to bring up system properties box select the performance tab and look at the system performance if % less than 30% windows enters the unstable zone
If system is low try reducing programmes running in the background by closing those on the sys tray or be adventuous and go for modifying your start up programme
For start up tab run "msconfig" in the run box
Hope this help
