J-BusinessDirectory - Page shift/jump with every popup box - and then back again on popup close

This is horrible to see, sorry, lol. I understand why it is happening (i.e. the popup box causes the scroll bar on the original underneath page to dissapear - which in turn causes the underneath page to shift right as the popup box appears - and then again, haha, shift left as the popup box is closed).

No this is terrible - we all know that it is the sign of poorly constructed html. Please can you find a way to resolve it. Otherwise just seems so amateur and lets what is obviously a (potentially, when it's properly finished off) fantastic script down.

Hi,

We could not reproduce this issue on our websites.
This can occur if there are some conflicts with the other extensions or the template used.
Please create a ticket on our store to investigate this.

Hi George, thank you for taking a look :)

However, I have checked the demo in three browsers, and on this page: http://demo.cmsjunkie.com/j-businessdirectory/directory/j-network/directory/listing-view/listing-view-style-3 if I select 'contact business' or 'quote request' the the site in the background shifts a bit on popup and close of pop-up.

I agree it's not a lot of shift, but when a site does this it is something I immediately - notice and count against it. Like I haven't noticed Facebook or Youtube doing it - or gmail or google :P
