Outlook express will crash because it a java based program that rely on the ram working correctly.
No offence meant here, but
all programs use RAM and rely on the physical memory working correctly. This has nothing to do with Java in particular, and additionally, since ep2002 has indicated that the problem is
only with OE, that would not point to a problem with RAM in general.
This might shed some light on the real root of the problem though:
The problems I have are w/ OE. If I search & find too many different e-mails, it starts to crash...
If your problems really are
only with OE, and you're also asking OE to deal with a very large number of messages, the cause is almost certainly
not due to bad or mismatched RAM, but rather the fact that Outlook Express has known limitations in terms of the maximum size of its folders (Inbox, etc.). Iif you have allowed a huge number of emails to pile up in your different OE folders, the program
will crash because you've exceeded (or are approaching exceeding) the size limit of those folders. The size limit on OE's files/folders was 2Gig last I checked, and I don't think that has changed recently.
