Together with described problem is not possible view preview of the page. I add printscreen for problem described above with edit of text object (I can see part of text ion the text object). I'm responssible for something about 15 web pages created by Incomedia Website so to solve this problem is very, very important.

Thanks Jan 

Hi Jan.

This seems like an issue usually caused by an interfering antivirus. Does this happen on a new project too?

Please try turning antivirus/firewall off temporarily, and restart your pc. Then, restart the software and see if the issue is now solved.

If it is, simply add the software to the Antivirus's exceptions and you should be able of turning it back on with no further issues

Let me know if this fixes it

Thank you

Stefano
