evosoft,
Sorry that you are seeing this issue. Thank you for the screenshot.
It looks like a corrupted workspace problem.
Can you please start MyEclipse with -clean command args and check if the issue persists?
If you are still seeing issues, then switch to a new workspace, import your project and check if it helps.
If none of the above suggestions help, then please share the .log file located at workspace dir/.metadata/.log for further investigation. Rename the extension to .txt and attach the file here.
Apologies for inconvenience caused. Do let us know how it works for you.
–Swapna
