Robohelp issues context sensitive help

I have created a context sensitive help using Robohelp now A, facing some issues.

I have lot of screen and from every screen i pass the topic id and call the funcation as  RH_ShowHelp(0, "WebHelp/index.htm", HH_HELP_CONTEXT, topicid);

In Chrome:

1. When I click on first time on any help icon it opens

2. When I click on second time on help icon without closing the first help window second window open but remains minmised

In IE:

1. When I click on first time on any help icon it opens

2. When I click on second time on help icon without closing the first help window second window open not as pop-up but in next tab

3. When I click on third time on help icon without closing the first and second help window third window open as blank
