You have provided more information for me to follow up on, so here goes.
First the easy stuff (doubtful, but we must start somewhere right?):
1. I have noticed that sometimes in XP SP2 that IE will include a yellow banner just under the toolbars which says it has blocked the popup, and if
you want the pop up to open, click here. (doubt if you overlooked this, but...)
2. Just use a workaround for the moment, like using a friend or family members pc to access your gmail, and invite others from it. (kinda sucks
but...)
3. "The pop-up blocker in Mozilla Firefox doesnt stop it from opening and I havent givent it permission. It just works." Ref:
GMAIL help forum (Therefore it is probably not a foxfire issue).
4. http:// to --> https:// solved the problem! Ref:
Forum GMAIL
issues(Also doubtful)
5. JavaScript and cookies must be enabled on all browsers. Ref:
Google GMAIL FAQ
(doubtful because if you had these off, you probably would not get to GMAIL in the first place)
Now the hard stuff (most likely or you would have fixed it yourself by now).
1. "If you got Norton internet security, 2001/2002/2003 or 2004 and possibly other versions as well, you can't open pop-ups in gmail like 'contacts
or the 'invites'. Symantec/Norton creators are aware of this, and are working on a solution. A simple solution would be for it to be automatically
off at GMail." Ref: Same as above
Some sites claim as above that you need to turn off the ad blocker, as you said that you did, AND IN ADDITION, set a rule within Norton to turn the ad
blocker off for that site. This is an issue with more sites than the gmail link from what I see.
Apparently Norton acknowledges this issue, and refers complaints about this problem to the following instructions:
Creating a rule to override Ad Blocking Ref:
not happy with norton. It stops our site even though we have no ad's
Here are the instructions:
Norton Internet Security 2001/2002/2003/2004
To create the rule Open Norton Internet Security. Open the list of Web sites:
Norton Internet Security 2003: Click Options. An options or properties dialog box appears. It has a tab titled "Web Content."
Norton Internet Security 2002: Click Options, then click Internet Security, then click Advanced Options. An options or properties dialog box appears.
It has a tab titled "Web."
Norton Internet Security 2001: Click Options, then click Advanced Options. An options or properties dialog box appears. It has a tab titled "Web."
Click the Web (or Web Content) tab. You see the Advanced Options dialog box:
Click Add Site. The "New Site/Domain" dialog box appears:
Type the site or domain name for the Web page that you want to create the rule for, then click OK. When you click OK, the new site appears highlighted
in the site list in the left column.
Norton Internet Security 2004 Open Norton Internet Security.
In the Norton Internet Security System Status window, double-click Ad Blocking. Click Advanced. Click Add Site. The "New Site/Domain" dialog box
appears: In the "New Site/Domain" window, type the site or domain name for the Web page that you want to create the rule for, then click OK. When
you click OK, the new site appears highlighted in the site list on the left.
Note: If Norton Internet Security does not accept the site name, type the entire URL except for http:// and the ending slash '/'. For example, for
the URL
www.symantec.com... type www.symantec.com
In the right frame, click Add. In the Add HTML string window, type the HTML string that you want allowed, and select Permit.
Whew, I hope the mod's allow this long post. Good Luck to you!
