Unable to open form links from ie7

Question

Hi,
apps:11.5.10.2
db: 11gR2
os:win2003
After database was upgraded to 11gr2, couple accounting department desktops (xp sp3 ) could not open SOME forms from ie7,
there was NO problem before upgrade.
1. Some forms can be opened and other can not be open after click. Turned on client java debug, trace option, nothing show up there after click
a form link. There are bunch of msg with working forms.
2. No errors I can find in apache access_log and error_log from these desktop IP.
3. I tried install newest version of Firefox on the desktop, it works beautiful and sleek.
4. I tried from other xp desktops, it works fine.
5. I tried from my laptop (win7+ie9), it works fine.
I did check out Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12 [ID 393931.1]
look for "Forms Launch Issues", no luck.
It got be something special on these two desktops, I have tried to clean ie cache, java cache, or even remove application data -sun folder, etc.
any body can help me or give me some hints?
I can turn on apache debug option on server to figure out what it is wrong (may be), but I would like a quick answer from anybody
has similar issue.
thanks
DW

Thanks Helio for reply.
There were something wrong with IE7 and Java JRE. The javaScript:Launchform under the links just would not launch jre and in turn to launch form. It was strange that some links
worked and some don't, after cleaned up IE cache, cookies, etc., the links that did not work before then worked and the ones that worked become not working. I restored the
whole XP box and IE7, then it works fine now.
I have another desktop has the similar problem, I removed and restored SP3 (XP) and IE7 instead of restore the whole box, it works fine.
IE is getting sucks, I have tried FF and Chrome on the same box, they were all worked great but IE7. I have tried many tricks I can found on IE7 and Java, none helps.
