Hi ,Using TS 6.5 Win 2000 SP4.I am calling callout for cross branch browser from DCT screen .Two queries :Ques 1 .The number of callout window that pops up on DCT screen depends upon the number of times we have clicked on callout button . Is there any way to put a check that only one callout window should be open at any given point of time . If a call-out window is open , then on further click on call-out button should not open more call-out windows ?NOTE : In case of TeamSite we have same functionality , ie., only one browser window is opened at any given point of time . If we click on browse button more than once ..then also we only one browse window open .Ques 2. Is there any way to disable the DCT screen when any callout windows appears ? After we have entered the value in callout sceen and clicked OK ( or anything ) on callout screen , then only DCT screen should be active ( So that when callout window is active no one should be able to make an entry in DCT screen unless he either cancel's or clicks OK on callout screen )Attaching screen shot .RegardsRohit Pathak
