Sorry that you are seeing this issue.
Can you please open a new window from menu: Window > New Window and check if the issue persists?
If the issue persists in the new window as well, then please close the IDE, delete the workbench.xmi located at/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi and start MyEclipse. Let us know how it works for you.
