Remind me of Rose.

By default, Rose is not automatically saved, but manually saved. I used to know that I didn't think so, so I didn't change it. I just saved it when I disabled it. After drawing a picture for more than half an hour today, rose suddenly got stuck and could not do anything .. I have always been reassured by Rose. After all, it's not just a niche software. I didn't think I had a cup of cake, and I couldn't help it. I called out the resource manager and forced it to close. The result is as you can imagine, I spent more than half an hour in vain, and I drew a new one. So it is better to save it automatically. Go to toools -- options and Check auto save.
Ever: Set the Automatic Storage Time. I set it to 5 minutes.

Some people say that rose cannot open multiple instances. In fact, it is okay, but it is different from everyone's usual habits. It is too inconvenient to open only one instance. I will teach you a method. It is very simple: Right-click the rese chart in the taskbar and click IBM Rational Rose Enterprise Edition. In this way, another editor is opened, click "file -- Open" to open the local MDL file. If you want to open a few files, you can open them. You don't have to worry about referring to others when drawing a picture.
