Gmail account verification gives a blank popup window

Gmail account verification gives a blank popup window

Hi all.
I tried to setup my zoho mail to use my gmail account.
I spend some time to understand first why each time I was trying to fill the requested informations for Gmail Zoho was always telling me "Already setup for this email ID" until I read that as soon as you're using a gmail.com domain everything is done for you automatically... cool.
Unfortunately I was able to send but not to receive. Please note that everything works already fine with my outlook 2007 agent, so all the necessary POP enabling setup are already done from Gmail side.
By the way I decided to delete my gmail id and to try to revalidate it...
This is exactly where new issues appears... each time I give back the validation code I got a blank popup window without any message... I tried with previous validation code this time I got a message asking me to give the right code (so a validation code can be used only one time...)
Unfortunately I'm totally unable to validate with the last sent code my gmail id and this one remains of course not accessible... I cannot change my default account to gmail.
Could you please help me, and check if something is going wrong from your side ?
Or tell me if I miss something.
Thanks for your help
