| Odd Behavior in Example RCP Projects [message #1042870] |

Hi, I am just starting out with RCP and am running into some odd behavior in the provided Plug-in Project Templates, particularly "RCP Mail Template" and "RCP Application with a view". The problems arise when these templates are unmodified.
First, when I run the RCP Mail project from "Launch an Eclipse application" and then add a few tabs to the folder view (via the plus button on the coolbar), then exit the program, then reopen it, everything is exactly the way it was when I exited the program. If I opened 5 tabs the last time I ran the program, there would be 5 open tabs the next time I run, regardless of the initial configuration set by the perspective. This holds true even if I restart Eclipse entirely.
Second, after starting and stopping the project a few times and manipulating the UI by adding and removing tabs in the folder, strange things start to happen. When I close a tab, sometimes two tabs close, or a new one will open. When I click on tabs, they will rearrange themselves. If I move a tab's order, my screen flickers (which is the scariest).
Occasionally I will get a Java error and stack trace. I have included an example at the bottom of this post.
These sound like memory management problems, which surprises me since I never run into those sort of problems in Java. Maybe the latest Java has a flaw? I am running on Windows 7.
Eclipse Info:
Eclipse for RCP and RAP Developers
Version: Juno Service Release 2
Build id: 20130225-0426
I also have one plugin installed: Window Builder Pro
I am quite perplexed and hope someone can tell me what I'm doing wrong. I have tried to create the project specifying older versions of Java and altering the settings with no luck. Again, these problems arise without any modification to the template. I just run the project I create from template.
Thank you in advance for your help!
