This is likely an installation / config problem. I’d suggest shuttind down Eclipse and starting eclipse.exe with the -clean option:
eclipse.exe -clean
If that doesn’t clear up the issue, can you please post all the information we request in the [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL] thread at the top of this forum? That will give us some context so that we can determine if this is an installation issue, a configuration problem, or a bug. Thanks.
