[news.eclipse.platform] Re: 3.4 (Mac) very slow to show right-click (context) menu 
Hi folks,

Okay I've just come up to speed on Mac Contextual Menu plugins, and have found the culprit. A beta application called "dropbox" (which performs folder syncing) installed a context menu plugin, the removal of which made this problem go away. I'll report this to them.

Hi guys,

I wondered if anyone else is seeing this. I couldn't find a bug about it.

I'm on OS X 10.5.4 (Intel), with latest updates.

When I right click on a Java source file in the Package Explorer, 4 times in 5, Eclipse performance will degrade to the mac beach ball (which I believe means that the app is no longer servicing its GUI event queue), for about 10 seconds. After the application returns, it cannot be raised using alt-tab, its icon must be clicked to raise it.

I'll attach the OS call stack at the end of this message. It mentions SVN*, so I suspected some native SVN library, but I'm using SVNKit 1.2.0 with Subversive.

Best regards,
-John
