luizromero,
Sorry that you are seeing this issue.
Can you please update your MyEclipse 10.6 to MyEclipse 10.7.1 ? Go to MyEclipse configuration center > Software tab, select “MyEclipse enterprise workbench 10.7.1” under software updates available section, click on Apply changes and follow the wizard.
The latest release of MyEclipse, MyEclipse 2013 (formerly known as MyEclipse 11) is now available. If you are having a licence for MyEclipse 10.x, then the same licence can be used for MyEclipse 2013, as our licences are time based not version based. For more information on MyEclipse 2013 and download links please take a look at this thread – https://www.genuitec.com/forums/topic/myeclipse-2013-is-now-available/
After updating to MyEclipse 10.7.1 or MyEclipse 2013, please open MyEclipse in a new workspace and import all your existing projects into new workspace and check whether you can replicate the issue ?
If you are still facing issues, can you restart MyEclipse using the -clean command and check if this works. https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/
Let us know how this works for you.
