Bug 149457

Description Frederik JOLY 2006-07-03 09:47:53 EDT

I'm trying to embed word in an applet following http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet157.java

It works when run from the applet viewer.

But when I try to call it from a web page, Word doesn't appear (but Word is present as the shorcuts are working, ctrl+f for find....)

the code is as follow :
