is there way identify close event , end peacefully or not show [x] option @ right top corner?

hi struggled past 3 days, , came conclusion of following:

these lines:

if (mainoptions["printmode"] == 'iframe') {   if ($.browser.opera || (/chrome/.test(navigator.useragent.tolowercase())))     mainoptions["printmode"] = 'popup'; } 

are obsoletes , seems cause issues in chrome, happens time when plugin created, chrome , opera have issues when printing iframe content.

as of today that's not longer issue (and since opera uses webkit chrome, must assume happens work on opera well).

so removes lines , notice print dialog not have blank window anymore, hence should not have problem.
