Affects Version/s: Aptana Studio 3.0.4
Fix Version/s: Aptana Studio 3.0.5
I've found an issue where just activating becomes pretty slow (current development version).
com.aptana.deploy.internal.ProjectPropertyTester.test(Object, String, Object, Object)
gets being called thousands of times after using the Aptana Studio a bit (to reproduce, open some .js editors and request the context menu some times, then move to another .js and request some more times – after that, just removing the focus from Aptana Studio to another application and back can become very slow – and the more it's used, the slower it gets).
Note that before activating the context menu the first time, that method isn't even called.
