Ralph, thank you for responding so quickly, I wrote down the versions below.
Etomite version: 1.1(prelude)
Server OS: Linux (fedora)
Apache version: 2.2.0
PHP version: 5.2.13
MySQL version: 5.0.90
When You mentionedother browsers, I started testing with different versions
First Internet Explorer 8.0, the problem is still there
Then Googgle Chrome, no problems at all, I'va created 10 snippets with php code, and they all were saved just fine.
The next days I will test some more, but it seems your idea of using different browers does the trick! Thanks a lot!
