TinyMCE editor not working

Hi,
I have a situation like the one in this snippet:

The text editor works fine if I stay on the TAB1 page (i can write, load and use all the TinyMCE tools with no problem), but if I go from TAB1 to TAB2 and then go back to TAB1 again, the editor does not work anymore, I can’t write and all the things I wrote before are lost.

How can i solve this problem?
