problem with OVS search help

i had developed a tabstrip in webdynpro abap . In one of the tabs i have some 10 input fields and 3 tables, Out of the 10 input fields 6 are having OVS search helps.

After i click on any OVS search help and get the value back to the screen , then the screen gets struck.
