# 4270 Access Violation in IDE after Moving and Closing Welcome Page

---

How to get it:

- start IDE
- open the welcome page (view/welcome page) if not already visible
- click&drag the welcome page tab, so it becomes the right most tab
- right/mouse on welcome page tab -> Close page

At this point I see a white plane in the IDE, no tab seemed to have focus.

- click on any other tab (of the loaded units/forms) to get the error message described.
