Just caught this reply...thank you for that. Seems that these jquery scripts are more stubborn than they seemingly should be. I've done as you suggested and the switch is not happening on chosen dropdown from the products page.
Now i have the product display page using a script for the hover and thumbs for the image (mod_vm_flexible_zoom_effect). If I remove the jquery script for this (easily done in the mod_vm_flexible_zoom_effect admin panel) the page reload will happen when I choose an item from the dropdown but of course there is no effect from flexible zoom.
I have even added jQuery.noConflict(); manually in the js file for the flexible zoom mod but nope, not working.
I love jquery functionality but these conflicts kill me...
really appreciate your feedback and insight. I will continue to mess around until a solution evolves...
