Explorer suddenly restarts.

hi,
when i am working, my explorer suddenly restarts. it is as if it got "overloaded with work" kind of a thing.
normally this happens when i try to open some file(i normally work with .txt's).
on oneMSBi's suggestion, i ran hijackthis. here is the log

hello busmaster. i checked over your log and i cant find anything amiss. maybe TomMyboy will spot something i did not. post this problem over at the windows forum, and let the best guys there see if they can help you out. [dont post the log there, just the problem details]

the only possible bad entry i could see was this:
O9 - Extra button: (no name) - {08B0E5C0-4FCB-11CF-AAA5-00401C608501} - (no file)
but i dont thinks its anything too bad.

Hi busmaster,

This line in your log:

O9 - Extra button: (no name) - {08B0E5C0-4FCB-11CF-AAA5-00401C608501} - (no file)

Is related to Sun Java and appears to have a problem. Do you know if MSJava has been properly removed before installing the Sun Java?

Also...

You are running without Windows Updates. It's kind of like running with scissors

Tom

wow. how did you know i didnt have updates?
anyway, i plan to reinstall my windows and upgrade to sp2 after my exams. next month.

regarding MSjava, if i remember correctly, i think, i had installed it first. and then i installed jdk much later to learn java. but i didnt remove MSjava.

[edit]
i think i know about the updates : the version and build number ???
[/edit]

the 3rd line of the log indicate you do not have any updates installed.

i dont think you need to re-install windows for now. I would suggest you un-install both Sun's java and MS java, completely first. then just re-install the sun java. see if the problem persists from then on.
